The comparison hub

Modeled exposure alone is a guess.
‍Observed exposure is evidence.

Every tool below scores your risk from a database. Spektion observes how software actually behaves at runtime. Five categories, one underlying difference, find the one that's in your stack.

Two questions sort all five: are you choosing between this tool and Spektion, or running both?
The split below tells you which.

Choosing between them and Spektion

Spektion replaces or sharpens these

Vulnerability scanners

Traditional vulnerability scanners

Best for programs that run a scanner, need better prioritization, and want vulnerability response shifted left of CVE disclosure.

Compare →
Exposure management

CTEM / exposure management

Best for programs evaluating attack-path modeling that want real conditions, not theoretical ones.

Compare →
Prioritization

RBVM / prioritization tools

Best for programs that want their risk-based prioritization to factor in runtime context and cover vulnerabilities outside the CVE catalog.

Compare →

You keep both

Spektion runs alongside these

AI security

AIDR

Best for programs evaluating tools that inspect prompts, responses, and agent tool calls.

Compare →
Endpoint security

EDR / XDR

Best for programs that want detection and response coverage for everything exploitable on the endpoint, not just no-context CVEs.

Why every one of these comes down to the same thing

Scanners, RBVM, and CTEM all model exposure. However sophisticated the math, the inputs are external or static: CVE records, global exploit data, installed inventory. None of them watch software run. EDR already proved that watching behavior beats matching signatures, but it watches for attacks in progress, and AI agent security governs agent permissions; neither answers what's exploitable. Spektion observes runtime to answer exactly that, and one source delivers what models can't: coverage past the CVE catalog (undisclosed vulnerabilities, vulnerable embedded components, stored secrets, insecure agentic workloads), context that determines both exploitability and impact (privilege, network behavior, usage patterns, what the software can reach), and intelligence generated inside your environment rather than inferred from someone else's data.

Scanners, RBVM, and CTEM model exposure from external data. Spektion observes it from runtime behavior.

Spektion provided us with unprecedented visibility into our software landscape. We leveraged their real-time vulnerability insights to implement a risk-based approach to managing our software inventory, allowing us to focus remediation efforts where they matter most.

FAQ

Questions teams ask

What does Spektion do?
Spektion is a more modern endpoint vulnerability management solution that goes beyond identifying CVEs. It provides the runtime context to prioritize patching and mitigation, identifies undisclosed vulnerabilities in software before a CVE is ever published, and shows how AI agents and internally built applications expand the attack surface where no CVE data exists. Spektion can replace an existing endpoint VM solution across every operating system, or sit alongside one to deliver the runtime evidence on exploitability that a CTEM program needs to work.
Does Spektion replace my existing tools?
It depends on which tool. For scanners, RBVM, and CTEM, Spektion can replace the endpoint scanning and prioritization layers or sharpen them with runtime evidence. For EDR and AI agent security, it runs alongside, covering exposure that those tools don't. The grid above sorts each comparison by which case applies.
Which comparison should I start with?
Start with the tool already in your stack that you're being asked to justify or expand. If you run a scanner and can't defend its prioritization, start there. If you're weighing an EDR vulnerability add-on, start with EDR. Each page goes deep on one category.
Is this the same as CTEM?
No. CTEM is a Gartner framework for continuously assessing attack surface. Spektion feeds a CTEM program the runtime evidence it needs but cannot generate on its own. See the CTEM comparison for details.
