Steve Lorimer - Group Privacy & Information Security Officer, Hexagon AB

Maintaining a team with high skills, and keeping that skill set current is very, very complicated if you're going to do it in-house. eSentire can bring that service to us, and we can benefit from the shared and the collective knowledge of the team.

Carl Maycock - Head of IT, Aston Villa Football Club

The way this works is we ingest our 24/7 logs into eSentire’s SOC. That gives us the ability to 24/7 monitor everything but more importantly to be able to react very quickly so when we have some sort of alert that comes through eSentire quickly alerts us to that.

What our employees are saying

What set eSentire apart from the rest of the companies is that they were one of the few pure-play cybersecurity companies in the region, and the only one with a local founder. I moved to Waterloo because I fell in love with the start-up culture, which you can see in all the unique coffee shops and restaurants uptown, and in the many successful tech start-ups. Even though eSentire was headquartered in Cambridge at the time, they embodied that same vibe. You can imagine how excited I was when we moved to Waterloo! I wanted to be part of something big, and I knew back then that eSentire was going to be big."
Jack Fahel
Product Manager
With eSentire, I always look forward to my day when going into work. I know I’m working in a fast-paced environment where there is always something new to see and learn. I work with people I like and trust and I know that I have the support of management to handle anything that may come up during my day. This is an industry that never stops and I feel there’s no better place to be part of that action."
Joseph Vansteenkiste
SOC Advanced Services Cybersecurity Specialist
I loved the company culture aspect of eSentire. After just my first interview in 2015 I could tell this was a place I wanted to work. Coming from a much larger company, I had always felt like just another number, at eSentire I was greeted on my first day by the Founder himself, mister Eldon Sprickerhoff. It is that kind of involvement, the leadership team had and continues to have that makes you feel valued and important, and I think that’s so special."
Kacey Hutchinson
Executive Assistant
When I reflect on my 5 years with eSentire three words spring to mind ‘Exciting’, ’Grateful’ and ‘Proud’. I find it Exciting to work in a company that is expanding so quickly, we are constantly changing and adapting to our customers needs and the Cybersecurity Landscape. Challenging the status quo is not only welcome but it is encouraged, I believe this is the reason we are the world leader in MDR! I am Grateful to witness the career development of so many SOC Analysts. Every week, month and year I can see their skill set improve and confidence grow. The icing on the cake is to see them transition into our advanced specialist teams, further growing their career with eSentire. I am very Proud to work in a company that is focused on important topics such as ‘Inclusion’ and ‘Nerodiversity’. We hire candidates based on their abilities and potential, we actively seek out alternative ways of thinking."
