The nice thing with eSentire is that they’re always looking at my network, my environment, and everything that’s coming through. I can sleep at night. I don’t need to have a 24/7 SOC. I know that my network is being looked at and if they see something that they deem to be a threat, they can prevent it, or block it and stop it, and get a hold of my team if needed.

We look at eSentire to be the experts. We trust them implicitly. One of the key differentiators I feel about eSentire in their response methodology is they’re with us through the thick and thin till the end so we're comfortable until the issue is resolved.

What our employees are saying

At eSentire, I have experienced a great deal of support and guidance as I build a career that aligns with my passions and core values. eSentire is an anomaly in the corporate world. The leadership team supports you as a person and encourages you to share your ideas, strengths, and talents on a global stage."
Mackenzie Van Eyk
Sales Enablement Instructional Designer
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
The senior leadership team is great at communicating our strategy and where the business is headed. It is a fast paced environment, but everyone finds the time to be transparent, open, and thoughtful about putting in place the right plans to help everyone succeed. Every team is very collaborative and wants to help."
Matthew Garrett
VP Corporate Marketing
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
Our leadership always keeps us up to date with announcements on our corporate goals and roadmap. There’s a lot of change in the cyberspace and we are never standing still. I can pause to reflect on everything we have accomplished together as a team and I’m excited about what we are going to achieve next."
Samantha Piotrowski
Sales Enablement Manager
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."
James Tierney
Manager, SOC Operations
Between the leading technology exposure and the encouraging and supportive work environment, eSentire has been one of the best workplace experiences I've had!"
Alex Epworth
Cybersecurity Specialist, SOC
I come from a scientific background and eSentire has provided a foundation for me to build a security career from while giving me the creative freedom to explore research and reporting topics that impact our client base. When I applied for permanent residency in Canada, eSentire was there to support me with the requirements and paperwork. Another great advantage of eSentire’s work culture is location mobility. I’ve been fortunate to have worked remotely for eSentire while I travelled across Canada, from Waterloo, Ontario to Whitehorse, Yukon."
