The Rising Importance of Human Expertise in Cybersecurity

Welcome to Part 1 of our three-part series, Driving Cyber Resilience with Human-Driven MDR: Insights from the 2024 Gartner Market Guide. This series explores how Critical Start’s Managed Detection and Response (MDR) solutions align with the key findings from the 2024 Gartner Market Guide for MDR. In this first installment, we delve into why human-driven MDR is essential for resilient security operations and how automated, technology-only approaches can leave organizations exposed to sophisticated threats.

Why Human Expertise is Crucial in Cybersecurity

Cyber threats today are more complex and frequent, often surpassing the detection capabilities of automated tools alone. While automation processes large volumes of data efficiently, human expertise adds critical context, strategic judgment, and situational awareness to threat detection and response. Critical Start’s MDR approach uniquely combines advanced technology with expert human analysis, ensuring sophisticated attacks are effectively detected, analyzed, and mitigated.

The 2024 Gartner Market Guide emphasizes the limitations of technology-only MDR solutions, which often lack the nuance needed to detect, prioritize, and respond to complex threats. By incorporating human-led analysis, organizations can better differentiate genuine threats from routine activity, reduce false positives, and strengthen their security posture.

Critical Start’s Human-Driven Approach

• Trusted Behavior Registry^® (TBR^®): TBR^® significantly reduces false positives by automatically resolving alerts for established known good and expected behaviors. This process prioritizes high-risk alerts for analyst review, maximizing efficiency.
• Skilled Analyst Review: Our security analysts handle complex alerts that require human interpretation, applying their expertise to assess threats within the context of your specific environment. This ensures that alerts aren’t just processed but are understood in the broader context of potential business impacts.
• Response Precision with Two-Person Integrity: For added accountability, we use two-person integrity reviews in our response actions, ensuring that each action aligns with each customer’s unique environment and operational requirements.

By combining automation with human expertise, Critical Start delivers efficient, accurate, and context-driven threat detection.

Mitigating the Risks of Technology-Only MDR Solutions

Gartner mentions that technology-only MDR solutions can inundate security teams with an unmanageable volume of alerts, leading to alert fatigue, delayed responses, and even missed threats. Critical Start addresses these issues by strategically pairing technology with human expertise..

Challenges with Pure Automation:

• Alert Fatigue: An overwhelming volume of automated alerts can strain security teams, resulting in missed or overlooked critical threats.
• Resource Waste: Without human oversight, organizations can waste valuable resources investigating false positives.
• Delayed Responses: Automation alone often lacks the strategic decision-making required for timely, appropriate threat response.
  

At Critical Start, our expert analysts enhance security operations by investigating complex alerts, making context-aware decisions, and executing tailored response actions. This human-driven approach ensures that genuine threats are swiftly identified, prioritized, and mitigated.

Human-Led Response for Faster Threat Containment
In fast-moving attack scenarios, quick threat isolation and containment are critical. While automated systems perform basic containment, human analysts offer distinct advantages, including understanding incident context, business impacts, and prioritizing appropriate response actions. Critical Start’s response capabilities include remote containment via MOBILESOC^®, allowing rapid threat isolation while minimizing operational impact. This tailored approach ensures that response actions are both swift and aligned with each customer’s operational requirements and risk tolerance.

Did You Know? Our Security Operations Center (SOC) analysts, supported by our Cyber Research Unit (CRU) and Cyber Incident Response Team (CIRT), are experts in identifying complex attack patterns that automated systems may overlook. This expertise ensures faster response times and more effective threat containment.

Building a Mature Security Posture Through Human-Driven MDR

As attackers refine their tactics, a mature security posture requires adaptive, intelligence-led responses. Human-driven MDR allows organizations to proactively enhance detection capabilities, applying new insights and adjusting to emerging threats. The 2024 Gartner Market Guide for MDR underscores the importance of human-led analysis in effective MDR, highlighting the growing demand for proactive threat identification beyond traditional detection and response.

At Critical Start, our Customer Success team conducts regular cyber risk reviews, providing tailored recommendations aligned with evolving security needs and operational priorities. This proactive engagement ensures that organizations not only meet today’s security challenges but also prepare for future threats.

In today’s complex cyber landscape, human expertise is indispensable for achieving cyber resilience. Critical Start’s human-driven MDR combines automated efficiency with expert analysis, offering organizations:

• Strategic and proactive threat management
• Expert-led investigation and response processes
• Accountability through two-person integrity reviews
