A Unique Approach to Cybersecurity

Technology will solve all your security problems.

Until it doesn’t.

For years, organizations believed that investing in more technology was the answer to their security challenges. In reality, companies were just adding technology on top of faulty security practices.

Recognizing the fundamental conflict between what organizations needed to address their security challenges and what the industry was telling them they needed, security executive Rob Davis founded CRITICALSTART in 2012 with a simple mission: to protect customers from cybersecurity attacks while reducing their risk.

Today, we continue to protect organizations of all sizes through our award-winning portfolio, which includes our Managed Detection and Response service, best-of-breed technology partners, and professional services.

Our Approach

For many, resources are limited, leaving you vulnerable to new and evolving cyberattacks. Our process helps secure your infrastructure on-premise or in the cloud, meet compliance standards, and reduce your exposure including:

MDR Services

Resolve every alert and stop breaches by investigating every security alert until they are classified as good or normal and can be safely resolved.

Assessment Services

Help you identify risks, document the effectiveness of your existing controls and create a roadmap to improve your security posture, including tools assessment, GRC/compliance guidance, adversarial simulation, and penetration testing.

Defense Services

Protect your endpoints and secure your environment, including endpoint security, next-generation firewall, SIEM, cloud security architecture,
V-CISO and vulnerability management.

Response Services

Reduce your incident response time and minimize the imapct of a breach, including IR and threat hunting.

Our Culture

Culture at CRITICALSTART is very important & everything we do is guided by these core principles:

Do What’s Right for the Customer.

Do What’s Right for our Employees.

Don’t Do Things That Suck.

Our Mission

Award-Winning Portfolio

“I would say that prior to the relationship with Critical Start, my SOC analysts were experiencing what we all call alert fatigue. Critical Start has really been able to reduce those alerts. Our SOC analysts are able to get through every alert they toss our way. I've been able to take our level three and level four analysts and put them back to work at what they were really hired to do.”
“I find the Critical Start SOC analysts to be very knowledgeable. We rarely get things escalated to us that I feel they should have dealt with. It's been a very good relationship. Not having an event is not making the newspaper in that negative fashion is very, very important to us. That's part of the big value.”
“Our previous Manage Detection and Response vendor didn't do anything. They didn't notify us and it was a big gap. Critical Start, is a complete opposite. What I see, I see stuff going in and I see it coming out; and I see it in a beautiful format.”
