Security and privacy in healthcare are obviously hot topics. So, when
Sentillion decided to sponsor HIStalk a few weeks ago, I pressed my
luck and asked for an interview with CEO and co-founder Rob Seliger. I
knew the company was refocusing a bit and also introducing a new single
sign-on application called expreSSO, so I offered as bait the chance to
talk about that. When I got on the phone with Rob, he said he'd be
happy to talk about anything and that we didn't have to pitch product.
Good answer.
When I hear either "single sign-on" or "CCOW", I think of Sentillion
first because they've been doing it for a long time. They've introduced
some new products I wasn't fully aware of, including the vThere
virtualized client for remote access.
Thanks to Rob for the chat.
Tell me about Sentillion
and how you came to create it.
Sentillion was founded in 1998, spun it out of the former HP medical
products group. I have the simplest resume on the planet –
paper route, HP for 18½ years, then Sentillion. [laughs] I
was working on technology that integrated applications not on the back
end, like databases and integration engines, but on the front end of
care, looking at the user experience of the caregiver, whether using
applications from the same or different vendors.
We determined that our technology would serve better as a glue, run as
a neutral company. We built a business case, they agreed. We spun the
IP out with myself and my co-founder in 1998. We did three rounds of
venture capital, the last one in 2001, and have been growing the
company every since.
We moved from general integration to specific applications used in
identity and access management. What we’ve been able to do is
create a whole suite of products that address identity and access
management needs for healthcare and, specifically, hospitals.
We sell to provider healthcare organizations. We’re unique in
that way. Our competitors sell to finance and banking and retail
customers. We said that healthcare has special needs, workflows,
idiosyncrasies, and constraints. We wanted to create technology that
was purpose-built for healthcare. Fast forward and we have hundreds of
thousands of caregivers in hundreds of hospitals in the US, Canada, UK.
Healthcare security, like
IT in general, seems to fall well behind that of most other industries,
with lack of consistent authentication rules across applications,
applications that don’t support LDAP or other centrally
managed security, and heavy help desk use for password resets. Is it
getting better?
It is getting better, but slowly. There are reasons why stronger
security technologies have not been broadly adopted in healthcare. The
main reason is that they get in the way of delivering healthcare.
I’m not a physician or nurse, but I have a tremendous respect
of what those people do for a living, taking care of people as their
number one job. Navigating security isn’t what
they’re paid to do. Our customer base is some of the
smartest, most highly trained people on the planet and
they’re adept at finding workarounds to impediments to
delivering care, including security.
Part of our process is leveraging the years of experience we have in
the care business. How many other security companies can you name that
have a chief medical officer? We hired Dr. Jonathan Leviss as our Chief
Medical Officer because he had a passion to eliminate the obstacles
between caregivers and the productive use of computers.
You’ve heard of the last mile problem, like with DSL, where
you can’t get connected if you’re too far from the
telephone switch. I refer to our situation as the last inch problem,
that inch that’s between the caregivers’ fingertips
and the keyboard they don’t use. We provide security
solutions that make them more productive instead of less, while
instilling better security practices across the organization.
People often say that healthcare is slow to adopt technology, yet you
can look at the amazing equipment from imaging systems to robotic
surgery that is used. I don’t see a fear of technology in
healthcare, just an avoidance of technology that’s an
impediment to healthcare delivery. Vendors often miss that. We work
really hard to get that right.
What security priorities
would you recommend to a hospital CIO?
My favorite thing to do if I’m allowed is to take a walk,
particularly in care areas, and watch what people are doing, who they
are, where the computers are, what they’re showing, and
whether they’re attended or unattended.
UPMC implemented our solution years ago. They started deployment in the
ICU. I was with an entourage of UPMC executives and I drifted back from
the tour group because they were headed to a workstation that someone
was using with single sign-on and single patient selection. I stood
back and marveled at all the workstations that were not in use, but
were locked. I asked UPMC when the last time was that all those
workstations with no one around were actually locked. [laughs]
It’s kind of like the broken window theory of why
neighborhoods go downhill. Good security isn’t just the
things you do on your network with firewalls and antivirus software. It
also has to do with what people can see. Show them that their
information is being safeguarded and protected. How would someone feel
being wheeled down the hall and seeing other people’s
information on display? It could be their information as well. You must
show personnel and patients that they’re doing the right
thing.
You testified before
Congress after the VA’s security breach. How would you grade
their progress since?
The hearings were for the right intentions but for the wrong reasons.
The breach that occurred with the theft of that laptop was benign. The
information was not clinical and the thief who stole it
didn’t know it was there. At the end of the day, it was a
non-event. They didn’t get Congress to the point of
understanding how to practice good security.
The VA has the same challenges as non-VA – security vs.
usability, however people who work for the VA can be told what to do,
which isn’t always true of community physicians in hospitals.
The VA has its act together as well as anyone else. They’re
continuing to make investments in practical security practices.
They’re extending a pilot we did for deployment of single
sign-on, which is the first step in a powerful direction for them.
The participation in that hearing was fascinating for me. It was
literally like being in a TV show. Members of Congress were in seats
elevated maybe 10 or 12 feet in the air, looking down at myself and my
VA colleagues at a table. Each member of Congress took the opportunity
to express a passionate opinion, not all of which were germane to the
conversation at hand. Despite the hyperbole, they actually listened to
what I said and what the VA said. They asked good questions. It was a
remarkable discourse.
The hearings were well after 9/11, yet the halls of Congress, with
minimal screening, are still very open to the public. It was a
wonderfully reassuring about our way of life. It was wide open to
people who wanted to come and listen and participate and not be overly
encumbered with security.
I’ve done so much public speaking that I’m rarely
nervous, but I was nervous. I would not want to be there for a serious
transgression or offense.
If I looked at your
laptop right now, what security measures would I find?
You’d find our product, Vergence, which is single sign-on and
a bunch of other things. Virtually everybody here uses it. What do I
like about it the best? I don’t have to remember my passwords
for the system that approves expense reports, Webex, salesforce.com ...
the list goes on and on. What I like best is the sheer convenience
factor. The screensaver periodically locks my workstation after about
15 minutes of unattended use. That happens whether I’m using
it at home or in the office. We all use high quality passwords,
mnemonics based on pass phrases, based on an elaborate sentence I can
remember and choose some letters from it to make my password.
Unless you’re sitting in front of it, you wouldn’t
see the display because of a 3M privacy protection screen. I was
working on board financials on an airplane flight several years ago
when the woman next to me leaned over, almost into my seat, and said,
“You know how to use a spreadsheet.” I thought,
“How long has she been watching me work on board
financials?” Anybody who’s a road warrior in the
company can have a privacy shield.
Security and privacy get confused. The woman looking over my shoulder
wasn’t trying to hack our systems, but she was breaching our
privacy as a company by looking at sensitive information. Both security
and privacy need proper protection. The recent George Clooney story
suggests that the concern is well founded that the biggest data access
concern that healthcare organizations should have is what happens
within their four walls. Too bad Palisades Medical Center
isn’t a Sentillion customer, as this is not a good way to get
one’s hospital in the news.
Are you happy with the
progress that healthcare software vendors have made in making their
products CCOW compliant for improving the user experience?
Interesting question. The general answer is no. We’ve put our
heart and soul into the CCOW standard going back to the HP days.
Standards in healthcare still have a fickle existence when it comes to
vendors adopting standards and applying them thoughtfully and properly
to their products and with the same interest as something that is
purely proprietary.
Much of the venture capital we raised in the early days was spent
giving market visibility to the CCOW standard. That helped to a point,
but there are vendors to this day who have not implemented the standard
or have done so in an incomplete way just to check off that
they’ve done it, or done it in an elitist way, interpreting
it in a way that’s good for their business interests but not
as useful to the customer as a full implementation.
Often a customer will say to us, “You’re
Sentillion, can’t you get Vendor X to do it
correctly?” I keep looking for that sheriff’s
shield or subpoena power to tell vendors what to do. [laughs]
We’re just another vendor.
Our answer was that so much of what was conceived by us and others in
the standard is extremely powerful, but if vendors won’t
implement it timely or correctly, we need another way. We developed a
technology called bridging that allows achieving the standard in a way
that’s not invasive to the application.
The A-Ha was that the part of the application we can see and rely on is
the user interface, as opposed to trying to inspect the application at
a code level and hoping for an undocumented API or secret hook that we
could latch on to. The user interface is tangible. Because that
translates into a series of calls to the underlying OS, we created
programs to watch for those calls. We can watch an application as the
user is using it and see that they selected a patient. We can get that
and send it to other parts of the application to automate patient
selection, but without having the CCOW standards.
I read something where someone said that CCOW is a great standard, but
that Sentillion controls it. Boy, did that rile me. I’ve been
doing this for over 15 years, originally for non-CCOW work. There are
very specific rules of engagement for a standards open development
process, from NIST, a standard for being a standard, how you vote, how
you achieve a quorum, etc. For an open standard, when you have a final
ballot, people can vote Yes, No, or Abstain. You throw out the Abstain
votes and 90% of what’s left has to be Yes for the standard
to be valid. Imagine trying to get that level of agreement in your own
family. [laughs] It’s a tough hurdle with lots of opinions,
lot of eyeballs before a ballot passes. There’s no way any
one organization can control a standard. They can be a blocker if they
have enough votes, but they can’t force something to happen.
If there’s a secret to what we’ve done,
it’s two things: show up to the meetings and document them.
[laughs] I like to write and most people don’t, so often it
is myself or others who volunteer to document the meetings, but that
doesn’t mean we’ve done anything more than spending
evenings and weekends to pull documents together for the greater good.
The idea that an individual or organization can control a standard is
unfounded.
When I Google Sentillion,
I get ads for ComputerProx and Encentuate. What is the Sentillion value
proposition over these and other competitors like Carefx?
The companies we’re most likely to compete with head to head
are more often companies like Novell or Computer Associates,
We’ll also see Imprivata. We don’t see a lot of
some of the other companies that come up with the ad hits, even though
they’ve latched onto the keywords. Across the board, for all
our competitors, there are really three salient points.
First is the healthcare focus. A CA or Novell, while they have sales
and marketing teams that cater to healthcare, have products that are
generic that are supposed to work in 9 to 5 office environments and not
necessarily healthcare.
Second, we believe strongly that we provide a fabric or glue. The last
thing we want our customers to have to do is glue our glue. If we show
up and say, “We have one piece of the puzzle and
you’ll have to work with these other vendors”,
that’s not particularly satisfying. That’s why
we’ve invested heavily in developing our own products. All
our products were developed by Sentillion so our customers would have a
single vendor, a single number to call. Every one of our competitors
requires multiple partners to do what we do as a single vendor.
Third is the incredible track record we have in getting customers live
and keeping them live. We have hundreds of hospitals and hundreds of
thousands of users. We monitor uptime across all customers and report
to our board like it was financial information. Five nines.
Who’s doing that for a security apparatus like we provide?
I hope you don’t think it’s bravado, it’s
just pride. There are still hospitals using monitors that I wrote
firmware for, like the HP Clover. I still feel pride when I walk by
them in a hospital and know that patients are being cared for with
something I wrote.
Why is desktop
virtualization important?
Going back to this sense of responsibility to solve problems, for years
our customers were asking us to help with people who are not physically
in their facility, like community docs or docs working at home. We told
them we could help to a point, but they’d have to build a
portal or provide remote emulation like Terminal Server or Citrix,
which requires an investment in servers and expertise. That’s
an OK answer, but not satisfying for customers.
We were developing improvements to our internal testing apparatus. We
do massive scalability tests to test response time and failure factors
and failover. We were experimenting with the virtualizing of clients,
not servers. 99% of what people are doing is on servers, putting
multiple virtual servers on one physical server. We thought,
“With a bit more work, we could provide a virtualized client
to our customers.” That was the birth of our vThere product.
Take the clinical workstation with whatever applications, OS, service
packs, etc. for people who are physically in your enterprise. You can
make exactly that same environment available to people outside your
organization. It’s transparent, no particular software
package or OS, or even preventatives or antivirus. You need a host PC
of a reasonably contemporary vintage running a reasonably contemporary
version of Windows. That’s it.
Fire up Windows and you get a completely virtualized version of the
clinical workstation running on the host using the host’s
memory and CPU, but no other aspect of the host software, If you use a
VPN, we use that. The user clicks on an icon, it runs in a window and
looks exactly like the application in a hospital. They provide their
logon credentials and everything is identical. Radiologists can
manipulate their images exactly like in the office without the remote
delays. There’s no training involved, no new portal, and no
additional expenses for standing up servers to host WTS or Citrix.
It’s all running on native client hardware.
We introduced vThere in the middle of 2006. Use ranges from physician
access to their full cadre of clinical applications to medical coders
who work at home, who have increasing clout because they stand between
the hospital and reimbursement. Hospitals are increasingly willing to
accommodate a work-life balance for coders. Customers are doing that
with IT, too, allowing them to work from home two or three days a week.
How can you provide with them their usual applications? Our vThere
product is a practical, elegant, and cost-effective solution.
Proximity-based security
and biometrics always seemed ideal for healthcare. Are they, and how
well are they selling?
We have extensive implementations of proximity and biometrics,
primarily in the US. Less so in Canada and in the UK, which has a
different model where NHS has mandated the use of smart cards. The
combination of active proximity and biometrics is very powerful. You
can achieve touchless logon. You walk up to a workstation, your
identity is provided to an active proximity device, and you are then
authenticated by fingerprint. With Vergence, our flagship product, we
can not only log you on, but automatically launch your applications
based on your role, and then single sign you onto those applications.
The first thing you need to do is select a patient – we
can’t read minds yet. [laughs] It’s very powerful.
Customers are using the technologies separately as well.
We introduced in the latest version of Vergence a variation on the
strong authentication theme using passive proximity devices and an
Enterprise Grace Period. Most healthcare environments are reasonably
physically secure. You can have flexibility in how you apply
authentication to users during the day. The user, at the beginning of
their grace period, swipes a proximity card, authenticates by password,
and does their business. The next time they need to log on, during the
grace period defined by the organization, they only need to swipe their
smart card. Possession of the smart card within the grace period tells
us it’s that user. Those seven or eight character strokes
done 50 to 100 per day times add up. It allows organizations to find
the right balance between strong authentication and caregiver
convenience.
How does expreSSO change
the single sign-on equation for healthcare customers and for Sentillion?
The biggest challenge that customers have with anybody’s
single sign-on always centers around connecting with the application.
Often, a vendor walks into a sales situation, tries to impress on the
customer how easy their tools make it, and shows a live demo.
They’ve thought through the applications to impress how easy
it is. For more complicated applications, or those developed in-house
with less optimal programming, what seems so easy in the sales call is
much harder.
We’ve taken everything we’ve learned to make it
easier to deploy. The next generation of tooling accompanies expreSSO.
A wizard allows organizations to create incredibly sophisticated
connectors without having to write code. If you think about a process
of creating a connector for signing on and off and dealing with other
sign-on related events, you’re navigating through a series of
screens and either inputting information on behalf of the users or
accepting information like a password expiration message. The trick is
to satisfy the application by putting in the right information at the
right time while responding to the information needed.
We looked at metaphors that would be easy for people to understand. We
decided to use editing a movie. Movies have frames, they flow in a
sequence, and you can insert special affects. We take a movie metaphor
and apply it to the process of having a user generate a connector to a
target application. We show screens in the order they want them to
appear and define inputs based on visual controls that they point and
click through -- for a logon, logoff, or password expiration message,
each representing the application as it appears at a certain point in
time.
Anybody that’s used iMovie or Microsoft’s movie
maker would instantly get how the expreSSO wizard makes connectors for
applications. My wife recently edited videos of my son, who’s
a competitive fencer. Colleges wanted 15 minutes of video. My wife went
through hours of movies, having a great time with iMovie creating
effects. She’s not a movie director, and had never used
iMovie before, but she was still able to use a tool to do very powerful
things.r That’s what expreSSO is all about.
The press release
mentions cost savings.
Vergence does an awfully lot more than single sign-on –
patient selection, auditing, and role-based access. Vergence is really
a platform for creating a complete clinical workstation. It’s
always been that, but in the early days, it was too broad for people to
understand that, so we positioned it as a single sign-on solution.
It’s like saying a car is an air conditioner when
it’s more than that, like an entertainment system and
transportation.
expreSSO does one thing really well and cost effectively –
signing on and signing off. Customers increasingly want to focus on
that to start and that’s what expreSSO is meant to solve
really, really, well. When they’re ready for a more
comprehensive solution, they can upgrade to Vergence.
You’ve had some
recent organizational changes, I’ve heard. What’s
going on at Sentillion?
We made some changes back in June that were mainly centered around
refocusing the company on healthcare. We had started a process with
vThere in broadening our footprint beyond healthcare in a thoughtful
way. We created a business unit inside of Sentillion to look at
opportunities outside of healthcare so the bulk of the company could
stick with healthcare.
It’s difficult for a $30 million company to do as many things
as we were trying to do. We were diversifying into the UK, bringing
vThere and expreSSO to market, and trying to establish a foothold for
vThere outside of healthcare. It was one vector too many. I decided we
needed to reconsider expanding outside of healthcare, or at least let
it be opportunistic and let companies find us. We had hired people
without the healthcare background because we didn’t need that.
We’ve just come off a terrific Q3, the first full quarter
since the change. We signed six new customers and sold a bunch of
products to existing customers. It was a good thing to do and we did it
thoughtfully for our customers and employees.
What do you like most and
least about being a CEO?
I thought I would miss writing code. My expertise is in distributed,
object-oriented programming. How’s that for a mouthful?
[laughs] I really don’t miss it. I find what I really enjoy
is the challenge of doing things that others haven’t done
before.
People often ask me about what I do other than work. I have a car that
I’ve been building for years. I drag race it. It’s
a combination of parts that have never been put together, which means I
make a lot of mistakes. I fine tune my problem solving skills and
persistence. The thing I love most is to see what others here are able
to accomplish that I have nothing to do with. It’s intensely
satisfying. It happens following ethical principles that we care about
and a corporate style that I care about, but I had nothing to do with
it.
What I like least is the set of arcane accounting rules that govern
software revenue recognition. It’s a set of principles
defined by accounting boards that software companies need to follow to
book revenue on an annual or quarterly basis. The rules are complex,
but accounting rules don’t have that foundation of reason.
It’s kind of like laws that evolved over the years. You can
spend an inordinate amount of time interpreting the rules so you do the
right thing. I’m not always sure that time is effective for
the business or customers, other than you want to do the right thing.
Who do you admire in the
industry?
The people that I admire most are in the new generation of CIOs,
probably in their late 30s or early 40s, who grew up with information
technology instead of having it happen around them. They have business
savvy as well. The combination of a comfort with IT and business savvy
are impressive.
Mark Hopkins at UPMC is one such person. Steve Hess of Christiana Care,
Praveen Chophra at Childrens Healthcare of Atlanta, Allana Cummings of
Children’s Omaha, and Marianne James of Children’s
Cincinnati. All of these are examples of healthcare CIOs who have a
comfort with technology and business acumen. They are putting it to
formidable use in their organizations.
I gave a lecture at HIMSS about the healthcare tipping point,
referencing Malcolm Gladwell’s book. One of the required
ingredients is people like this to make it happen. If healthcare IT
becomes truly pervasive in the next five years, it will be because of
people like this.
Thanks for sponsoring
HIStalk, by the way.
What was most fun about sponsoring your blog is that we all reading it
already. It was a Homer Simpson Doh! moment. The best endorsement is
that we didn’t just hear about it and decided to sponsor.
Just like we use our product, we were already reading your blog.
