The Critical Start difference

We reduce risk acceptance, improve productivity—while accelerating ROI—for cybersecurity.

Technology will solve all your security problems. Until it doesn’t.

These are all great technologies, but they must have an effective strategy and process to tie them all together, combined with an elite team to find the flaws and fix the vulnerabilities in a cybersecurity environment. Otherwise, these tools just perform “good enough.” And good enough typically falls painfully short at the precise moment of a breach.

Managed Detection and Response (MDR) services can provide that strategy and process, but only if it also doesn’t settle for anything less than stellar performance. That means treating all alerts as equal and never accepting risk as part of the cost of doing business. That’s why our security experts built a system, platform and service that quickly detects every event, resolves every alert and stops breaches.

Our approach

“Services that don’t suck.” That sums up our approach in a nutshell. While that statement may seem simple, it’s the result of years of complex and sophisticated refinement to provide superior on-premise, or in the cloud, security services. If you’re evaluating your own state-of-security, and want to understand what Critical Start can offer, ask yourself the following:

Good enough…isn’t.

Every alert is important because every alert tells a story. And that story can stop a threat. So, stop settling for so-called good security that just prioritizes alerts and allows real intruders to fall through the cracks.

Detect every threat. Resolve every alert. Stop breaches.

Am I missing important alerts?

Critical Start MDR services bi-directionally integrate with market-leading Endpoint Detection and Response (EDR), Endpoint Protection Platform (EPP), Security Information and Event Management (SIEM) tools to protect your environment. Our trust-oriented approach leverages the Zero Trust Analytics Platform™ (ZTAP®) to collect, understand, and resolve every alert. ZTAP strengthens our investigation of unknown alerts to ensure the escalation of the alerts that really require the attention of your security team. And our Trusted Behavior Registry™ (TBR) reduces false positives by enabling us to auto-resolve false positives—the largest volume of alerts—at scale.

I’m breached. Now what?

When your organization is under attack, immediate response is critical. Critical Start specialists help you protect your environment with a customized plan and early detection, then we reduce your incident response time to minimize the impact of a breach.

    I find the Critical Start 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.

    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… I’ve been able to take our level three and four analysts and put them back to work at what they were hired to do.
