Overview
Key Findings
Adversarial exposure validation (AEV) solutions use a variety of testing techniques that aid in reaching outcomes such as a better defensive posture, prioritized exposure awareness, and greater readiness for attack scenarios.
AEV continues to be a maturing technology area, and vendors are taking diverse approaches to solving customer exposure validation challenges. Some vendors specialize in only a few outcomes, whereas others cover a broader range.
Many organizations fall short in conducting frequent and consistent offensive security testing, largely because it is complex to orchestrate and demands specialized skill sets. As a result, essential security gaps remain unaddressed. AEV technologies are key to overcoming these challenges, as they reduce skill and complexity barriers, enabling organizations to test their defenses more effectively and proactively.
Recent focus on integration capabilities has created robust automated workflows, lowering barriers to entry. This automation fosters collaboration, streamlines operations and increases efficiency, while also enhancing the relevance and effectiveness of testing scenarios.
Recommendations
Prioritize validation outcomes, such as improved defensive posture, exposure awareness or attack scenario readiness, to guide your AEV tool selection and required capabilities.
Optimize cybersecurity investments by using AEV solutions to validate actual state of readiness (the ability to detect, respond and recover) against current and emerging threat scenarios, thereby supporting evidence-based decisions.
Conduct validation testing on a regular cadence to create trending metrics that reflect your ability to find, prioritize and remediate exposure or readiness gaps related to attack scenarios that are rapidly evolving and occurring more frequently.
Scale red teaming activities by using solutions that provide workbenches for building attack scenarios and help codify and automate manual validation tasks.
Gain greater visibility into the actual priority of exposures or attack scenarios by actively testing attack paths to determine which ones lead to real, organization-specific impact.
Market Definition
Gartner defines adversarial exposure validation (AEV) as technologies that deliver consistent, continuous and automated evidence of the feasibility of an attack. These technologies confirm how potential attack techniques would successfully exploit an organization and circumvent prevention and detection security controls. They achieve this by performing attack scenarios and modeling or measuring the outcome to prove the existence and exploitability of exposures. AEV is generally delivered as a SaaS solution with or without on-premises agents.
AEV as a market category replaces breach and attack simulation (BAS) and automated penetration testing and red teaming technology from the 2023 Gartner Hype Cycle (Hype Cycle for Security Operations, 2023). AEV technologies provide automated execution of both simplified and/or extensible attack scenarios. Results data from an executed attack scenario is used for various outcomes, such as: validating a theoretical exposure as real, automating frequent controls testing, improving preventive security posture or improving detection and response capabilities.
AEV technologies can achieve some or all of the common exposure validation outcomes by:
Supporting an organization’s strategic decision to shift from ad hoc testing to a more continuous exposure validation that enables continuous threat exposure management (CTEM) programs.
Providing blue teams with a defender’s advantage by quickly assessing how their defensive posture withstands various attack scenarios and techniques within their actual environment and level of exposure. This data is helpful for:
Detection stack tuning
Preventive posture changes
Exposure prioritization
Service provider performance validation
Security vendor performance scorecards
Other operations or controls improvements
Allowing offensive testing teams the ability to create custom attack scenarios and multistaged attacks designed to either validate complex threats or attempt to defeat current defensive systems. They can also leverage automation for various tasks associated with red team testing, which can increase the team’s scale and reach.
Mandatory Features
The mandatory features for this market include:
Performing attack scenarios for multiple threat vectors, including but not limited to: malware, email, application infrastructure, and application and identity abuses. Delivered outputs include: security-framework-aligned reporting, attack scoring, and prioritized lists of attack scenario findings with estimated impact and suggested remediation actions.
Providing empirical results about an organization’s defensive posture as it relates to various attack techniques and scenarios. The validation results data should greatly improve upon other more theoretical data (such as vulnerability data) and give insights into urgently needed changes.
Ability to scale defensive testing with vendor-supplied attack scenarios that require little to no hacking knowledge to execute and obtain results data.
Automated scheduling for increased testing frequency without the need for human intervention, helping to reduce errors and improve trending measurability data for exposure management and defensive operations.

Market Direction
Security operations performance relies on evidence and data about how technologies, processes, service contracts and human resources are functioning. AEV solutions provide cybersecurity leaders with that data by performing a range of validation use cases. The market has evolved due to:
The value that these solutions bring to an organization depends on which use cases the organization wishes to embrace. For some organizations, the need to reduce threat exposure by implementing continuous threat exposure management (CTEM) is the primary justification for the AEV solution. Other organizations with larger investments in tools, teams and service partnerships seek AEV data to improve the efficiency of staff, processes and security controls. In other words, they are looking to justify, with data, why a change is necessary.
For many organizations that are dealing with the outputs of a traditional vulnerability management (VM) program, the volume of findings is high. Validation techniques allow security operations teams to reduce that volume by confirming and prioritizing findings through offensive-testing techniques. Traditionally, the process of validating a finding through a red team exercise or a penetration test has been not only high-impact but also time- and labor-intensive. AEV technologies aim to replicate and provide consistent, automated and targeted validation of prioritized exposures quickly and accurately, without a persistent need for specialized testing skill sets, enabling closed-loop mobilization.
Market Analysis
AEV solutions appeal to organizations with more mature security operations, more offensive capabilities or those in highly regulated industries. Structured and repeatable offensive capabilities offer high value, as measuring and justifying spend on offensive activities is challenging, and use cases regularly evolve. However, the latter point also helps justify the decision to acquire a technology to govern and productize testing across a diverse set of capabilities.
Organizations have the most success with AEV when justifying spend for the following initiatives:
Ultimately, validation solutions answer key questions about top strategic initiatives for cybersecurity leaders, such as product performance, team and service-provider-contract performance, and risk relative to exposure or defensive capabilities.
An essential part of a validation solution is having a method of operation that leads to (mostly) nonrefutable results. Vendors widely use frameworks, such as MITRE’s ATT&CK and threat-informed defense (TID), as a common taxonomy to relate their findings in a simplified format across a range of devices.
AEV solutions are different from other testing solutions, such as exposure assessment platforms (EAPs) (see Magic Quadrant for Exposure Assessment Platforms). EAP solutions continuously discover, assess and prioritize exposures with context such as business, asset criticality and threats that pose the greatest risk, commonly covering all assets in an environment. In contrast, AEV solutions tend to focus on proving exploitation of high-value vulnerabilities or threat scenarios that lead to successful attacks related to their validation functions.
EAP solutions provide broader and more up-to-date information about exposures, and some can predict the likelihood and potential impact of exploitation through passive modeling. However, they can’t offer direct evidence on whether the vulnerability or other exposure is actually exploitable within an organization’s security posture/controls. They also can’t provide context on the blast radius of the exposure. By contrast, AEV solutions’ validation takes a “closed loop” approach to getting results.
For example, suppose an EAP solution found a system to be, in fact, exposed and vulnerable. The AEV solution could then:
This approach helps better prioritize patching and mobilizes findings to defensive teams more quickly.
Architecture and Deployment
AEV is primarily delivered as a SaaS platform that centralizes the scheduling, execution, and reporting of attack scenarios, offering:
Centralized control: The SaaS console acts as a control plane for orchestrating simulations, visualizing attack paths, accessing remediation and mitigation guidance, and integrating with the broader security stack for workflow automation.
Point of attack (PoA): Externally hosted PoA systems for “outside-in” attack simulation and internal PoA systems for “inside-out” scenarios, ensuring coverage of both external and internal threats.
Attack workbench: Advanced platforms feature an attack creation workbench, enabling customization of scenarios and multistage attack chains through data ingestion, generative AI or manual scripting.
AEV platforms increasingly leverage AI to improve scalability, adaptability, and operational relevance by incorporating LLMs and AI agents within the control plane to assist with scenario selection, prioritization and interpretation of results to support decision making.
AEV platforms support flexible deployment architectures including agent-based, agentless and hybrid models:
Agent-based: Installs lightweight agents on endpoints and servers for simulation.
Agentless: Uses authenticated access or APIs or self-contained test packages to test assets without additional software installation, enabling rapid and frictionless deployment.
Hybrid: Combines agent-based and agentless methods to maximize coverage and flexibility across diverse environments.
AEV platforms support multiple execution environments that determine where validation occurs:
Digital twin: A replica of the production environment that mirrors relevant assets, identities, configurations, traffic and security controls. Digital twins enable safe execution against high‑risk or mission‑critical assets without impacting live operations.
Live, production environment: Validation activities are executed directly against production systems using controlled, nondisruptive techniques where operational risk is acceptable.
Pricing and Licensing
Comparing pricing from multiple AEV vendors is challenging, as many different pricing models are possible. In Gartner’s observation, the majority of the pricing models in the market are based on either:
Overall pricing will likely include other pricing model factors as well, such as:
Gartner recommends comparing competitive pricing by using a common means of assessment such as price per asset or price per user. You can further evaluate pricing differences by layering on a secondary factor such as advanced features.
Gartner observes that most buyers use a “crawl, walk, run” approach to purchase AEV products. That is, they control cost by limiting deployments and setting key value milestones before making further purchases.
AEV Market Drivers
Movement to CTEM
The continuous nature of a CTEM program necessitates frequent and consistent testing. The capability to repeat testing on a scheduled basis — running orchestrated testing playbooks and reporting findings regularly — aids in the early identification of exposures, misconfigurations, new shadow IT and even updated threat techniques.
AEV delivers validation through two levels of approaches:
Adversarial simulation: Simulation mimics a broad range of adversary tactics, techniques, and procedures (TTPs) using automated, repeatable attack scenarios to assess how security controls perform across the environment. This approach prioritizes breadth and coverage, enabling organizations to efficiently test many attack paths and identify systemic detection and prevention gaps.
Adversarial emulation: Emulation focuses on depth and realism by replicating the behaviors, sequencing, and decision‑making patterns of specific real‑world threat actors based on threat intelligence. Emulation tests how an attacker would adapt to deployed defenses and whether identified exposures can be chained and operationalized into a successful campaign.
A combination of both approaches is recommended for scalable coverage and targeted emulation of high-risk scenarios.
Not all vulnerabilities are patchable. AEV solutions provide organizations with options to mobilize remedies for validated issues. By consuming data from monitoring systems, AEV solutions can identify exploit scenarios that are successful and also invisible to SOC teams. They can increase the priority of such issues and provide treatment suggestions beyond just patching software.
Demand for Scaling Internal Red Teams
Creating in-house red teams for more intensive internalized testing continues to be a popular topic. Although interest is high, many cybersecurity leaders struggle to justify the cost of building an internal team of dedicated, highly skilled testers. Therefore, they outsource many penetration testing and red teaming functions to a third-party provider/consultant.
AEV solutions present an opportunity for cybersecurity leaders to better scale red teaming functions via technology platform features that support threat validation. Generative AI (GenAI), cybersecurity AI assistants and emerging agentic AI solutions can make red teaming operations more economical and can possibly reduce the entry-level skill set required as well.
A lot of the work performed by red teams could be characterized as developing a relationship between very large, yet different, datasets in order to find an avenue of attack. Tools like GenAI have proven to be effective at summarizing, comparing and determining meaningful connections, and predicting high-priority attack scenarios by synthesizing information from sources such as threat intelligence, exposure data, and attack scenario results. AEV tools often use frameworks, such as Lockheed Martin’s Cyber Kill Chain, to help guide content development.
Instead of relying on human effort to create testing cases, other solutions feed raw threat intelligence reports into GenAI and agentic AI orchestration engines to build attack scenarios. Solutions powered by GenAI tools can extract relevant indicators from the reports and generate content to create a testing scenario. However, solutions using GenAI tools will not be able to build business-aligned attack scenarios if they have only limited knowledge of the function and importance of different business applications.
Any such application of scaling technologies that reduces the operational overhead or skills required to build an offensive security team would evolve the AEV market.

Market Recommendations
AEV is a disruptive trend in the security operations markets. The following are pragmatic guidelines that cybersecurity leaders should consider before acquiring this technology.
Define Measurable Outcomes Before Starting Vendor Selection
Because AEV capabilities vary widely, AEV vendors may support some outcomes better than others. Gartner recommends that you start with one of the predefined use cases listed in Figure 1. Next, focus on the desired outcomes you wish to obtain as part of your project success criteria. Trying to reach all three outcomes at once will likely require a much greater project scope and a much longer time to succeed.
Consume AEV as Part of a PTaaS Subscription If You’re Understaffed
Penetration testing as a service (PTaaS) is an adjacent market to AEV (see Innovation Insight: Penetration Testing as a Service). Similar to AEV, PTaaS providers offer a range of testing and validation services on a more periodic basis. Some of these services include not only penetration testing but also control validation and exposure management. PTaaS is attractive to organizations that require frequent adversarial exposure validation but lack the in-house expertise to operate the toolsets.
This model provides scalability and flexibility, allowing businesses to adjust the scope and frequency of testing based on their specific needs and resources. PTaaS providers are, by definition, service providers. As such, they primarily offer their services on top of their own technology platforms and don’t require the organization to purchase an AEV tool. This business model makes PTaaS an ideal choice for organizations with limited security resources, enabling them to maintain a robust security posture without significant infrastructure investment.
Build AEV Acquisition Based on Provable Justifications
Organizations have very different reasons for allotting budget to AEV solutions.
The following are common for AEV purchase justifications:
Some organizations are concerned about security gaps emerging during application development and deployment. AEV solutions can be integrated throughout the software development life cycle (SDLC) to continuously validate controls and identify vulnerabilities early, ensuring ongoing protection of applications as they evolve.
Organizations may have an initiative to start, or increase the performance of, an internal red team. Although AEV is not the only tool required to operate a red team, it often presents a rightsized solution for starting or moderately improving a practice.
Start With Defense Optimization If You’re Unsure Where to Begin
If you are unsure about which outcome is best for your organization, Gartner suggests starting with defensive optimization or the fundamentals of a blue team practice. Although having a red team sounds more appealing, it’s not for everyone, and the results are often more elusive to prove.
The premise of defensive optimization is twofold:
Having consistent testing data not only shows how well your investments are working, but also shows when they aren’t. This information can:
AEV tools don’t require advanced skill sets to operate for defensive optimization, adding to the outcome success of defensive optimization over other use cases.
Consider Open Source to Gain Visibility Into the Value of Commercial AEV Solutions
A number of open-source, AEV-like solutions are available, such as Atomic Red Team (see atomicredteam.io) and MITRE Caldera (see Caldera). If you are not sure whether an AEV solution will provide value to your organization, you can sometimes gain visibility into use cases and reporting data by testing with open source. Open-source outcomes can also help justify a business case to expand AEV through a commercial solution.
However, open-source solutions take a fair amount of time and skill to function and often produce limited results. Consider this option a last resort, if your effort to fund a commercial AEV solution lacks the evidence it needs to get started.
