How we got started

(not in a garage… but in a barn)

It was a tweet. ¯\_(ツ)_/¯ Seriously, when co-founders Dave Merkel, Yanek Korff and Justin Bajko saw @rickhholland tweet back in late 2015 that MSSP customers had endured “the customer service equiv. of taxi drivers” they saw an opportunity.

What we found

(alerts without any good answers)

Digging deeper, we saw three big problems that were dragging the security industry down.

  • Too many confusing security products delivering reams of alerts
  • Not enough security talent to prioritize the alerts and effectively manage the risk
  • MSSPs who had failed to deliver on their promises

And there were no good solutions. Some companies were looking at managed detection and response (MDR) providers – but MDRs added a new expense without replacing MSSPs. Most customers were suffering in silence with no alternative.

“I think the MSSP market is ripe for disruption. Many have had the customer service equiv of taxi drivers, customers aren’t happy.”

Our vision

(it’s a bit unorthodox but we DO believe that you can love security)

Cloud

Remember how IT used to run wires and rack servers? Thanks to cloud computing and web services they don’t do that anymore.

Alert

But if you’re in security you still spend the majority of your time in the weeds massaging alerts and operating products. Or worse, you can’t afford (or find) the people and technology to even do that.

Idea

We want to flip that equation and create space for you to do what you love about security (even if that’s thinking about it as littleas possible).

Our approach

(so radical we had to talk ourselves into it)

We think our approach is pretty unique. It starts with transparency. We’re busting up the proprietary black-box approach that MSSPs and MDR providers take. In our hold-your-cards-close-to-your-chest industry that’s the radical part.

Here’s what we do…

  1. We use the security products you’ve already bought
  2. Our analysts investigate alerts and monitor your environment
  3. When we find a problem we tell you exactly what to do about it
  4. We also tell you how to fix the root cause of problems that happen over and over

…that’s it!

Transparency means that you can look behind the curtain while we’re doing ^this^ and see anything (or everything) our analysts are doing for you 24x7 while they’re doing it. Heck, we’ve even built it so you can even jump in and work collaboratively with our analysts if you want. Either way, we’ll give you answers to these questions (not more alerts).

What’s happening in my environment

What do I need to care about and why?

How do I resolve this incident?

How can I become more resilient?

Dave Merkel

Dave Merkel

Chief Executive Officer

Dave Merkel (aka “Merk”) is the co-founder of Expel as well as the company’s chief executive officer. He’s ultimately responsible for everything and has been frequently mistaken for Willy Wonka.

Dave has been involved in the information security field for nearly 20 years, first as a federal agent pursuing cyber criminals in the era of floppy disks and 2400 baud modems, then as chief technology officer (CTO) and vice president of products at Mandiant. Following FireEye’s acquisition of Mandiant, Dave served as the global CTO of FireEye.

Before Dave’s 10 years as a solutions provider he spent another decade as a security practitioner. He got his start as a special agent in the Air Force Office of Special Investigations, pursuing cyber criminals and conducting digital forensic investigations, and later as head of AOL’s technical security organization. While at AOL, he created and ran the first incident response capability for AOL and Time Warner, managed software security and policy programs, and built technologies for AOL’s security infrastructure.

Prior to Expel, Yanek was the vice president of Mandiant’s managed services business which helped customers mitigate the consequences of security breaches. Yanek established and  grew the service to become one of the first follow-the-sun managed detection and response (MDR) providers, accounting for over 30 percent of Mandiant’s revenue. Following Mandiant’s acquisition by FireEye, Yanek served as CTO of FireEye as a Service, FireEye’s managed services offering.

Prior to Mandiant, Yanek was responsible for the majority of AOL’s security infrastructure including authentication, authorization management, public key infrastructure (PKI) and systems that supported incident response, e-discovery and investigations.

Denise Hayman

Denise Hayman

Chief Revenue Officer

Denise Hayman is our Chief Revenue Officer. If you’re looking to learn more about Expel, chances are that you’ll be talking to her or someone on her team. She’s also passionate about making sure that your experience is better than it was for any other security product you’ve bought.

She comes to Expel with more than 25 years experience seeing security (and sales) done right, wrong and every shade in between. Prior to Expel, she was vice president of global security sales at Neustar where she built out a sales team that helped customers protect themselves from the evils of DDOS and IP attacks.

Denise got her start in sales at Symantec. Over her career she returned to the endpoint behemoth twice as it gobbled up two of the companies where she went on to head up sales: Vontu, a pioneer in data loss prevention (DLP) and disc encryption vendor PGP.

She’s also built and led sales teams at Tripwire, Cyphort, Norse (there’s a good story about that one – just ask her), and Vendavo. She likes to say she was trained at Symantec and then followed the data (and attackers) as they used the internet (and now cloud apps and infrastructure) to compromise organizations in creative new ways.

Denise is passionate about building diverse sales teams (including women) which know that honesty, transparency and “doing the right thing” for customers isn’t just good business … it’s essential to their own reputation.

She’s working hard to get more women in sales and wants women everywhere to know that you can build a successful sales culture without having the uncomfortable sameness that exists without diversity.

She has a B.A. from Boston College.

Justin Bajko

Justin Bajko

VP Strategy and Business Development

Justin Bajko is a co-founder of Expel as well as our VP of Strategy and Business Development. It’s Justin’s job to stay close to our customers and partners and make sure that we’re heading in the right direction. He also spends a good bit of his free time fretting about the University of Tennessee’s football program.

Justin has been involved in information security and managed services since just after the turn of the century. Prior to Expel, he was senior director of global service delivery for FireEye’s managed service, FireEye as a Service. Justin was responsible for building and managing FireEye’s security operations centers (SOCs) around the world, including a staff of more than 80 analysts.

Prior to FireEye, Justin was the managing director for Mandiant’s Managed Defense service, one of the industry’s first managed detection and response (MDR) providers. Before that, Justin worked at Symantec where he worked in a number of roles within their managed services business ranging from SOC engineer to senior manager of the global threat response team where he was responsible for detection capabilities, intelligence integration, and customer data ingestion for Symantec’s MSSP customers worldwide.

Justin hails from northeast Tennessee. In his free time he enjoys anything to do with cars (spending an inordinate amount of time making sure his are always clean) or boats, traveling, and playing an embarrassing amount of video games.

Peter-Silberman

Pete Silberman

Chief Technology Officer

Peter Silberman is the chief technology officer (CTO) at Expel. Peter splits his time between ensuring Expel has a robust detection and response strategy for all its technical partners/integrations and making sure that Expel is pushing the envelope with new ways to improve analyst experience and efficiency. He works to achieve this while also driving new service capabilities built on top of those integrations. Expel’s exceptional team of engineers get to do all the code writing (the fun stuff!). He gets to write docs and draw pictures for others (the
not-as-fun-as-coding-but-necessary stuff).

Before joining Expel, Peter was the senior director of Innovation and Customer Engineering (ICE) at FireEye. He helped create what’s now known as the FireEye Data Science Group. He worked to deliver new capabilities impacting all aspects of the company’s product portfolio. This includes building technologies to automate various tasks faced by responders, reverse engineers and SOC analysts. Peter spent some of his focus researching memory forensics, finding new artifacts that could be used for detection and response.

Peter often presents his original research at industry conferences including CanSecWest, DefCon, HITB, Black Hat and RSA. He continues to focus on discovering new and efficient ways to automate the repetitive tasks that machines do better than humans, so that humans focus on what they do best – making judgement calls and building relationships that improve customers’ experience.

If you skipped down to this section we don’t blame you. Our analysts are at the heart of everything Expel does. They monitor your environment, chase down issues and keep you safe. We put a lot of careful thought and effort into the way we hire, train and promote our analysts. Here’s a glimpse (fyi… we have more than three) at some of the people behind the service.
