Proactively uncover and defend against advanced attacks. Our experienced cyberthreat hunters leverage AI and threat intelligence to see early warning signs and prevent breaches.

Why It Matters

Security operations teams are overwhelmed

Adversaries‌ constantly devise new ways to attack your organization. Not every threat is equal, and not every attack vector is relevant, yet SOC analysts must wade through a sea of alerts. As they do so, they struggle to distill all that security data into actionable insights to detect sophisticated attacks.

 

What should your defenders focus on? How do you keep up proactive defense with limited personnel? How do you ensure everyone, from your CISO to junior analysts, is working in lockstep on the most impactful threat defense initiatives?

 

Our expert-led managed threat hunting can help.

FAQ

Threat hunting is a proactive approach to finding potential threats and vulnerabilities in an organization's network and systems. It combines security analysts, threat intelligence, and advanced technologies that analyze behavior, spot anomalies, and identify indicators of compromise (IOCs) to detect what traditional security tools may miss. They strive to detect and neutralize threats early to minimize their potential impact. Learn more.

Threat intelligence is the collection, analysis, and dissemination of information about suspected, emerging, and active cyberthreats, including vulnerabilities, threat actors’ tactics, techniques, and procedures (TTPs), and indicators of compromise (IOCs). Security teams use it to identify and mitigate risk, reinforce security controls, and inform proactive incident response. Learn more.
