Breach & Attack Simulation Tools: A Comprehensive Buyer’s Guide
Breach & Attack Simulation (BAS) tools can be a significant investment, making the selection of the right product crucial. This guide aims to assist in that decision-making process.

Breach & Attack Simulation tools provide insight into the effectiveness of security controls.
Breach & Attack Simulation (BAS) solutions help organizations understand their security posture. These tools automate the testing of specific threat vectors, often based on frameworks like MITRE ATT&CK or the Cyber Kill Chain. BAS products can simulate:
- Network attacks and infiltration attempts,
- Lateral Movement,
- Phishing,
- Endpoint and gateway attacks,
- Malware and ransomware attacks, and
- Insider threats.
Understanding Breach & Attack Simulation
Breach & Attack Simulation can complement Red Teaming, Penetration Testing, or Attack Surface Assessments (ASA), but it differs significantly from these measures. Consider an organization as a villa:
- Red Teaming or Penetration Testing involves hiring someone to break into the property and empty the safe. The goal is to uncover potential access points.
- Breach & Attack Simulation, on the other hand, is like checking all the locks on the doors for functionality and ensuring that installed security cameras react appropriately when they detect people. The goal is to ensure all control measures function as intended.
- While BAS focuses on enterprise security controls like EDR, Attack Surface Assessment examines all potential vulnerabilities and attack vectors.
Gartner, the analyst firm, categorizes these technologies under the broader term “Exposure Management.” According to analysts, Breach & Attack Simulation solutions are particularly in demand in highly regulated sectors like banking and insurance, which face increasing compliance requirements. Ilja Rabinovich, Director of Adversarial Tactics at security provider Sygnia, confirms this assessment: “BAS products are typically expensive and are not acquired by smaller companies with limited budgets or restricted process landscapes.”
The Market for Breach & Attack Simulation Tools
Gartner analysts predict that over 40 percent of all organizations will rely on consolidated platforms or Managed Service Providers for cybersecurity validation by 2026. The BAS vendor landscape is correspondingly diverse, with standalone providers, large security companies, and service providers offering their BAS solutions. Chirag Mehta, an analyst at Constellation Research, foresees further market consolidation: “If a tool can simulate attacks, the next logical step is to prevent them. However, this requires integrating a range of different tools, which is not an easy task.”
A growing trend in IT security, as in other areas, is the use of Generative AI (GenAI). Erik Nost, an analyst at Forrester Research, views this development positively: “We will likely see generative AI first implemented in the user interface. Interacting with data in a cool way is the new GenAI use case.”
The analyst also considers it possible that AI could model threats based on data or the most relevant attack types for users or the company. He adds: “Generative AI could also be used to help organizations understand problems found by BAS, set appropriate priorities, and suggest specific remediation measures.”

According to Expert Insights, AttackIQ’s central emulation platform replicates attacker tactics, techniques, and methods in alignment with the MITRE ATT&CK framework. The company’s Breach & Attack Simulation offering is divided into three options:
- The managed platform “Ready!” aims to help organizations achieve a consistent security validation strategy more quickly and easily.
- The agentless testing service “Flex” operates on-demand and is billed on a pay-as-you-go, monthly, or annual basis.
- “Enterprise” is a comprehensive co-managed service.
AttackIQ has also gained recognition for testing ML and AI-based cybersecurity components. The company states it is the only BAS provider offering both self-service and full-service solutions. In the future, artificial intelligence is expected to further assist AttackIQ customers in automatically identifying and remediating security vulnerabilities.
According to Expert Insights, Cymulate is a leading provider for Continuous Threat Exposure Management and also holds the best customer ratings on Gartner’s Peer Insights, partly due to its positive user experience. Cymulate’s “Breach and Attack (BAS)” solution is delivered via a SaaS model. A private tenancy option is also available for organizations with data segregation requirements. Like AttackIQ, Cymulate uses the MITRE ATT&CK Framework as its foundation.
The provider states that it currently takes approximately three to four weeks to set up integrations and deploy its BAS tool. Cymulate aims to reduce this timeframe to just a few minutes with the help of Generative AI. The provider’s GenAI plans extend further: the technology is intended to automatically develop mitigation strategies from thousands or even hundreds of thousands of different attack scenarios and explain how these should be implemented to security teams. Cymulate expects its GenAI features to be fully available by the end of October 2024.
Fortinet’s BAS offering does not quite match the customer ratings of the first two providers. However, “FortiTester” combines Breach & Attack Simulation with network performance testing, offering a comprehensive solution. The Fortinet tool simulates various attack types based on the MITRE ATT&CK Framework and, according to Expert Insights, also supports CVE-based IPS tests and DDoS traffic generation.
Security provider Mandiant is primarily known for its Threat Intelligence services. This expertise is integrated into its BAS software solution, “Security Validation,” which sets it apart from competitors. The Mandiant tool supports features such as MITRE ATT&CK Framework mapping, automated alerting, and environmental drift detection, simulating real-world attack scenarios.
