Proactively identify zero-day vulnerabilities before they are exploited
Prevent zero-day attacks from breaking through

of successful data breaches result from new or unknown zero-day exploits2
of zero-day exploits are driven by
A zero-day attack takes advantage of an unknown exploit in the wild that exposes a vulnerability in software or hardware that cybercriminals use to gain access into your environment.
This combination of information and ability is used by threat actors to launch cyberattacks with devastating impact, such as ransomware deployment, service disruption, and data theft.
Zero-day vulnerabilities are challenging for organizations of all sizes to defend against. They can last for weeks or months before they are detected and investigated, which can finally alert the software vendor to develop a patch.
Zero-Day Attack Mitigation: How eSentire Reduces the Risk of Zero-Day Attacks
Although zero-day attack detection is ideal, it’s not realistic simply due to the nature of the zero-day threat itself. However, just because you can’t detect a zero-day exploit, it doesn’t mean there’s no defense against these threats.
As soon as a new zero-day vulnerability or exploit is discovered, we can help your team proactively identify if your organization is at risk through our eSentire Vulnerability Management service. In addition, we also provide ongoing 24/7 Threat Hunting, proactive Indicator of Compromise (IOC) sweeps, and complete response with eSentire Managed Detection and Response (MDR) to prevent your business ever being disrupted.
Zero-day attack detection identifies vulnerabilities across traditional and dynamic IT assets so you have continuous visibility into your expanding business environment.
We focus on vulnerabilities that present the greatest risk to you. You benefit from expert guidance to ensure you’re prioritizing the remediation of these dangerous exploits.
eSentire MDR combines cutting-edge Extended Detection and Response (XDR) technology, multi-signal threat intelligence and the industry’s only 24/7 Elite Threat Hunters to detect and contain zero-day attacks on your behalf.
We minimize the attacker dwell time with a Mean Time to Contain of 15 minutes. Once a threat has been isolated and remediated, we work with you to return affected environments to standard operations.
Our Threat Response Unit (TRU) proactively researches emerging threats, including zero-days, and operationalizes proactive global threat hunts across our entire customer base as part of our core MDR offering. eSentire TRU is foundational to our MDR service – no add-ons or additional costs required.
TRU proactively hunts and builds new detection models leveraging the power of artificial intelligence pattern recognition to drive new intelligence, containment and response actions across our XDR Cloud Platform.
TRU has been on the frontlines for zero-day attack detection for some of the most dangerous threats and nation-state cyberattacks.
Watch this video with one of eSentire’s top threat researchers, Spence Hutchinson, as he reviews the Kaseya VSA supply chain attacks. Spence outlines how eSentire’s Security Operations Center (SOC) and Threat Response Unit (TRU) were able to quickly respond on our customer’s behalf and notify Kaseya of the breaches.
In these attacks, threat actors leveraged zero-day vulnerabilities to push Cryptomining malware and ransomware to Kaseya VSA customers. Our proprietary BlueSteel Machine Learning Engine identified malicious Powershell commands being executed. eSentire’s actions to detect, respond and remediate these attacks demonstrate the importance of MDR services that go beyond alerting and host isolation to deliver complete & robust response.LEARN MORE ABOUT ESENTIRE’S THREAT RESPONSE UNIT →
Whether or not a newly discovered vulnerability will lead to widespread exploitation is dependent on who discovered it. Zero-day vulnerabilities are most commonly discovered by:
Cybersecurity researchers, who discover vulnerabilities so they can be patched before they can be exploited by adversaries. These researchers may be a part of the software vendors’ in-house team or cybersecurity practitioners who work in-house at organizations.
White hat researchers, who first notify the software vendors of vulnerabilities so they can be patched before publishing the research at a later date.
Nation-state researchers, who discover vulnerabilities that pose a risk to national security, in which case they may notify the relevant software vendors. However, nation-state researchers may also choose not to notify the software vendor if the goal is to exploit the vulnerability for the national interest.
Black hat researchers, whose primary aim is to develop exploits that can be used for malicious purposes.
Once the zero-day vulnerability is discovered, a threat actor must know how to exploit it. Some vulnerabilities are easily exploitable, requiring only slight modifications to existing attack tools, while others are much more complex. With this latter group, there is often a series of incremental steps:
Vulnerability is discovered
Proof-of-concept (PoC) demonstrates the viability of exploitation
Exploit is weaponized in a practical technique
Exploit weaponization and tooling is optimized
Once weaponized, an exploit may be used exclusively by a particular threat actor or sold on Dark Web marketplaces.
When a cybersecurity researcher revealed three ProxyShell zero-day vulnerabilities and how they could be exploited on Microsoft Exchange servers. Once the technical vulnerability details were released, cybercriminals began to determine how they could exploit the ProxyShell vulnerabilities.
eSentire TRU was able to coordinate with our 24/7 SOC Cyber Analysts to proactively identify if any customers were impacted by the vulnerabilities, develop detections based on the Indicators of Compromise (IOCs), and perform global threat hunts for ProxyShell.
In December 2021, security researchers released details and Proof-of-Concept (PoC) exploit code for Remote Code Execution of a vulnerability impacting the Apache Log4j Java-based logging library. There were also reports in the wild of the Log4j exploitation resulting in ransomware deployments.
Shortly after, eSentire TRU conducted scanning for the vulnerability, Cobalt Strike activity, and crypto mining payloads in addition to the targeting of web servers.
In response, TRU coordinated with our 24/7 SOC Cyber Analysts to proactively identify if any customers were impacted by the vulnerabilities, developed detections based on the Indicators of Compromise (IOCs), and conducted proactive global threat hunts for Log4j.
Not all MDR is created equal. When a zero-day attack is identified, the right Response and Remediation make the difference. Learn more about the Response and Remediation you can expect from eSentire.
Without leveraging a comprehensive vulnerability management program and 24/7 multi-signal MDR, it’s easy for threat actors to exploit the latest CVEs and zero-days to deploy ransomware and malware in your environment.
