CTEM vendors in 2026: 10 exposure management platforms compared

CTEM (continuous threat exposure management) is the Gartner framework for running exposure work as a continuous program, in five stages: scoping, discovery, prioritization, validation and mobilization.

Vendors now sell into CTEM from two directions. Exposure assessment platforms pull findings and threat context into one view of risk. Exposure validation platforms test whether an attacker could actually use what was found.

Here are 10 CTEM vendors, each described from its own product pages and documentation, plus Tamnoon, the cloud remediation platform that fixes what they find.

Six exposure assessment platforms

These platforms cover discovery and prioritization: they inventory the attack surface and rank findings by risk.

Tenable One

Tenable One is Tenable’s exposure management platform. Tenable says it unifies security visibility, insight and action across the attack surface.

• Coverage spans IT assets, OT and IoT devices, cloud resources, AI assets, containers, web apps, code repositories and identity systems
• Attack path visualizations correlate signals across domains to find toxic risk combinations that lead to sensitive systems and data
• Tenable Hexa AI runs an always-on fleet of AI agents to investigate cross-domain risks and coordinate remediation
• Bundles Vulnerability Management, Web App Scanning, Cloud Exposure, Identity Exposure and Attack Surface Management

Qualys Enterprise TruRisk Management

Qualys documents Enterprise TruRisk Management (ETM) as the technology foundation of its Risk Operations Center (ROC), an operational framework for continuously measuring and reducing cyber risk.

• Pulls risk and asset data from Qualys applications (VMDR, CSAM, Policy Audit, WAS) and from third-party tools into one view
• Enriches findings with 25+ threat feeds and scores them with TruRisk, which applies the Qualys Detection Score and asset criticality
• Cyber risk quantification converts technical findings into financial impact
• Guides remediation by risk appetite, business entity hierarchy and impact thresholds

Rapid7 Exposure Command

Rapid7 positions Exposure Command as hybrid exposure management: vulnerability management widened with attack surface context and cloud and application risk in one platform.

• Prioritizes exposures by exploit likelihood, reachability, severity and business context
• Combines Rapid7 vulnerability telemetry with third-party data, through 500+ integrations across cloud, identity, ITSM, ticketing, EDR and CI/CD
• No-code automation handles remediation and ticketing
• The Ultimate tier adds multi-cloud visibility across AWS, Azure, GCP and Kubernetes, IaC scanning, automated cloud remediation and dynamic application security testing

CrowdStrike Falcon Exposure Management

CrowdStrike says Falcon Exposure Management continuously finds exploitable vulnerabilities and attack paths and prioritizes fixes with adversary intelligence.

• The Exposure Prioritization Agent ranks what attackers are most likely to exploit and why, using exploitability analysis, adversary intelligence, attack path analysis and asset context
• Visibility across external assets, endpoints, cloud, network, OT/IoT and shadow AI, with exposure insights connected to remediation and response workflows

Microsoft Security Exposure Management

Microsoft’s documentation describes Security Exposure Management as a unified view of security posture across company assets and workloads.

• The enterprise exposure graph and attack surface map can be queried across on-premises, hybrid and multicloud environments, including Azure, AWS and GCP
• Attack paths include hybrid paths that span on-premises and cloud, with choke points where many paths flow through
• A Resolve Now view lists prioritized Patch, Mitigate and Fix items for internet-exposed and business-critical assets
• Connectors bring in third-party data, including ServiceNow CMDB, Tenable, Qualys and Rapid7
• Available in public cloud only, not in national or sovereign clouds

Cortex Exposure Management by Palo Alto Networks

Palo Alto Networks introduces Cortex Exposure Management as AI-driven prioritization and automated remediation spanning enterprise and cloud.

• Prioritizes high-risk, exploitable vulnerabilities that have no compensating controls
• AI-written plain-language summaries and native playbook automation guide remediation, and new protections for critical risks can be created in Palo Alto Networks network and cloud security products

Four exposure validation platforms

These platforms cover validation: they test which exposures an attacker could exploit, so the riskiest ones get fixed first.

XM Cyber

XM Cyber says its Continuous Exposure Management Platform supports the CTEM framework by delivering exposure assessment and exposure validation in a single platform.

• Attack Graph Analysis shows the attack paths that lead to critical assets, in the cloud or on-premises
• Directs fixes to choke points, where one exposure carries multiple attack paths
• Covers CVEs and misconfigurations as well as identity and access exposures
• Identity exposure management watches for configuration drift and hidden lateral movement paths

Pentera

The Pentera Platform runs AI-driven adversarial testing in production to validate exploitability and prioritize remediation.

• Consolidates alerts into a handful of validated root-cause issues and re-tests after automated remediation
• Tests internal networks, external assets, cloud and hybrid environments
• Pentera says the platform supports all five CTEM stages, with security validation at the core
• Pentera describes its adversarial emulation as safe-by-design

Cymulate

Cymulate describes its platform as continuous exposure validation, with its Vero AI tailoring tests to your environment.

• Continuous threat and attack simulation is mapped to MITRE ATT&CK, with daily threat updates from Cymulate Research Labs
• Security controls optimization analyzes how controls respond to threats and orchestrates updates across the security stack
• Vero AI maps SIEM rules to attack scenarios to validate coverage and tune detection logic
• Built to automate validation inside a continuous threat exposure management program

Picus Security

Picus says the specialized AI agents in its Autonomous Exposure Validation Platform validate exposures and security controls as one loop, with autonomy you tune from manual to fully autonomous.

• Tests whether an exploit chain would actually succeed against your controls, in your environment
• Deprioritizes exposures that existing controls already block

Where Tamnoon fits: the mobilization stage

The platforms above decide which exposures matter. Mobilization, the last CTEM stage, is where those exposures get remediated, and it is often the trickiest part because it requires real organizational change.

Naming the exposure is the easy half. Closing it safely is the other.

Tamnoon

Tamnoon is a cloud remediation platform, the self-healing engine for cloud exposures. Tamnoon sits downstream of the tools you already run.

• Reads findings from scanners including Tenable Cloud Security, Qualys TotalCloud, CrowdStrike Falcon, Defender for Cloud and Cortex Cloud
• Closes what is safe to close through your own controls and declines the rest in writing
• Covers misconfigurations, vulnerable workloads, identities and exposed data, from any scanner
• Fixes are written IaC-aware, so they survive the next apply
• Every decision becomes a receipt

The scanner stays. The queue finally moves. Book a demo: 30 minutes, read-only.

CTEM FAQ

What is CTEM?

CTEM (continuous threat exposure management) is a cybersecurity process framework introduced by Gartner. A CTEM program runs in five stages: scoping, discovery, prioritization, validation and mobilization. Read the full definition in our CTEM guide.

What is the difference between exposure assessment and exposure validation?

Exposure assessment platforms bring findings and threat context into one prioritized view of risk. Exposure validation platforms test whether an attacker could realistically use a gap in your environment. XM Cyber delivers both in one platform.

Do CTEM platforms fix the exposures they find?

Several platforms on this list now add remediation guidance or automation. Tamnoon works alongside your exposure management platform and fixes what it surfaces.

Which CTEM vendors does Tamnoon work with?

Tamnoon reads findings from Tenable Cloud Security, Qualys TotalCloud, CrowdStrike Falcon, Defender for Cloud and Cortex Cloud, products from five of the vendors on this list.
