Threat Response Solutions

Reclaim The Advantage Over Sophisticated Cybercriminals

Modern threat response requires the ability to collect unstructured data from disparate sources associated with attacker tactics, techniques, and procedures (TTPs) and operationalize global protections – all in a timely manner.

Unfortunately, many in-house security teams don't have the bandwidth or expertise to perform proactive threat hunting, conduct original threat research, and develop or deploy new threat detection rules.

The eSentire Threat Response Unit (TRU) is an industry-leading threat research team committed to helping your organization become more resilient. This is an elite team of threat hunters and researchers that supports our 24/7 Security Operations Centers (SOCs), builds threat detection models across the eSentire XDR Cloud Platform, and works as an extension of your security team to continuously improve our Managed Detection and Response service.

By providing complete visibility across your attack surface and performing global threat sweeps and proactive hypothesis-driven threat hunts augmented by original threat research, we are laser-focused on defending your organization against known and unknown threats.

We prioritize creating and updating our detection rules and machine learning (ML) models regularly, so your security posture is hardened against the evolving threat landscape. Our content development is built upon the MITRE ATT&CK Framework® and is constantly fine-tuned for efficacy to reduce false positives.

eSentire’s
Threat Response Unit

TRU acts as an extension of your security team to build your cyber resilience and prevent business disruption. With TRU by your side, you can rest easy knowing that you’re protected by an MDR provider that law enforcement agencies rely on to identify threat actors and collaborate on threat intelligence.

Prepare and react to emerging, unknown cyber threats to prevent business disruption

TRU continuously monitors the threat landscape, publishes regular threat advisories, security bulletins, and threat intelligence reports, and conducts proactive real-time threat hunts so you can stay ahead of the latest emerging threats and prevent business disruption.

Harden your toolkit with novel threat detection rules and advanced ML models

As a foundational component of the eSentire MDR service, TRU constantly builds and updates new threat detection rules and ML models across our eSentire XDR platform. These detections are further strengthened by robust investigative runbooks to support our SOC Cyber Analysts in their investigation and containment actions – on your behalf.

Go into battle with a team of industry veterans with real-world experience

TRU has discovered dangerous cyber threats and nation-state attacks (e.g., the Kaseya MSP breach and identities of hackers behind the more_eggs malware). With a 95% employee retention rate, TRU consists of highly certified, seasoned industry veterans who regularly hold threat briefings, share their expertise with industry publications, and have proven to be trusted sources for global law enforcement agencies.

WE OWN THE R IN MDR

See eSentire in Action

An effective defensive posture requires process, technology and most importantly human expertise for combat-level containment and response. You can’t battle these types of cyberattacks alone. Learn how eSentire MDR responded to emerging threats, including zero-day and ransomware attacks, with a balance of automated platform disruptions and hands-on expertise for investigation & manual cyber threat containment.

Notable Threat Detections

WE STOP THREAT ACTORS IN THEIR TRACKS. OTHERS CLAIM IT, WE PROVE IT.

Our Threat Response Unit (TRU) collects and processes threat intelligence from 37+ commercial threat feeds and 10+ proprietary intel sources, the Dark Web, social media, security reports, positive SOC-driven threat investigations, and various third-party tools to conduct further investigations and identify potential Indicators of Compromise (IOCs).

Once a threat is discovered, eSentire TRU publishes regular threat advisories, security bulletins, and threat intelligence reports, and conducts proactive real-time threat hunts so you can stay ahead of the latest emerging threats and prevent business disruption.

eSentire TRU has discovered some of the most dangerous cyber threats and nation-state attacks in our space. Last year, TRU built 520+ new detectors to protect our customers and circulated 44 Security Advisories. We broke the news on the Kaseya MSP breach, the malicious more_eggs malware and more.
