Vulnerability management has long been a cornerstone of enterprise security programs, but it addresses only part of the problem. A continuous risk-based process focused on identifying and remediating security weaknesses in IT systems, applications, and networks, vulnerability management typically centers on CVEs, leaving misconfigurations, expired certificates, and compliance deviations outside its scope.
Exposure management changes that. As Tanium Domain Architect Greg Lacroix explains, exposure management is a continuous, threat-informed process aimed at identifying, correlating, and reducing all forms of security exposure across the entire environment, not just known vulnerabilities.
Greg walks through the five-step exposure management lifecycle (scoping, discovery, prioritization, validation, and mobilization) and demonstrates how the Tanium platform supports these phases from a single console. The demo covers Tanium Benchmark's enterprise risk dashboards, compliance findings in Comply, policy enforcement using CIS bundle kits and STIG GPOs in Enforce, third-party application vulnerability analysis with EPSS scores and confidence scores, and operating system patching informed by exploit intelligence including weaponization status and public availability of exploit code.
If your team is managing vulnerability and compliance workflows across separate tools and separate teams, this episode shows what a unified, autonomous exposure management approach looks like in practice, and why reducing mean time to remediate (MTTR) depends on breaking those silos. Watch the full episode below.
Key takeaways
- Exposure management vs. vulnerability management: Vulnerability management is a continuous risk-based process focused on identifying, assessing, prioritizing, and remediating security weaknesses inside IT systems, applications, or networks. Exposure management expands that scope to include misconfigurations, expired certificates, compliance deviations, and more, not only CVEs.
“So vulnerability management is basically a continuous risk-based process, and its aim is to identify, assess, prioritize, and remediate security weakness inside the IT system, application, or networks. Exposure management is a continuous threat informed process, and its aim is identifying, correlating and reducing all form of security exposure across the entire environ months. It's not only focusing on CVEs, but it's also looking to expand the scope to include like misconfigurations identify the risk in general, like the expired certificate or compliance deviations.”Tanium Domain Architect Greg Lacroix
- Five-step exposure management lifecycle: The lifecycle separates into five distinct steps: scoping (identifying what needs to be protected), discovery (identifying where exposure exists), prioritization (deciding when to act), validation (verifying whether an exposure is exploitable), and mobilization (determining who will fix it and how).
- Benchmark for immediate posture visibility: Tanium Benchmark provides a real-time, data-driven snapshot of an organization's current security posture, covering compliance failures, vulnerabilities, certificates, and lateral movement, giving teams the visibility needed to support prioritization and mobilization.
- Pivoting from Benchmark to Comply for compliance remediation: Teams can pivot directly from a compliance failure identified in Benchmark into Tanium Comply to get additional contextual information about specific rules, including the actual value observed on the device, the expected state, and step-by-step remediation guidance explaining why the failure occurred and what to do next.
- Endpoint criticality as a prioritization factor: Not all endpoints carry the same risk. Endpoint criticality (whether a device is a critical server, an Active Directory server, or a test workstation) directly informs how compliance failures and vulnerabilities should be prioritized, ensuring remediation effort is focused where the risk is highest.
- Policy enforcement with CIS and STIG configurations: Tanium Enforce allows teams to import CIS bundle kits and STIG GPOs directly, create policies for specific operating systems, and automatically enforce those configurations on devices, so the next time a machine is scanned, the deviation can be remediated automatically as part of an autonomous exposure management approach.
- Third-party application vulnerabilities with EPSS and confidence scores: Third-party applications like Adobe Reader, Java, and Office are common sources of vulnerability. Tanium surfaces EPSS scores to help prioritize which vulnerabilities associated with those applications are most likely to be exploited, and provides a confidence score indicating the predicted likelihood that a software deployment can succeed with minimal issues.
“EPSS is the likelihood of how a vulnerability could be exploited over the next 30 days. The score is between zero and one. So zero point 85 is quite high, but there is a high percentage of risk that this vulnerability will be exploited suit.”Tanium Domain Architect Greg Lacroix
- Exploit intelligence for OS patching decisions: When remediating operating system vulnerabilities, Tanium surfaces exploit intelligence including total exploits identified, maximum maturity, whether an exploit has been weaponized, and whether exploit code is publicly or commercially available. That context helps teams prioritize a CVE with a high EPSS score over one that is severe but has no known public exploit. In some cases, a single cumulative update can remediate a large number of CVEs across affected endpoints, making a single remediation action highly valuable.
“For me, what is really important here in this autonomous exposure management approach is breaking the silos. This is really a philosophy of how you need to think: you need to know your environment, you need to know what's running, where you have some risk, where you have some vulnerabilities, some exposure in place. And from there, discussing and having some prioritization in place with the operation teams that will remediate the actions, so we are ready—through a single platform and breaking the silos—to fix and to reduce the risk in the environment.”Tanium Domain Architect Greg Lacroix
- Breaking silos to reduce MTTR: The goal of autonomous exposure management is to reduce MTTR, or the time between when a vulnerability is found and when it is actually fixed, by centralizing visibility, prioritization, and remediation in a single platform, reducing the need for separate teams and tools to manage compliance, patching, and endpoint health independently.
