# Best Breach and Attack Simulation (BAS) Software - Page 4 *By [Brandon Summers-Miller](https://research.g2.com/insights/author/brandon-summers-miller)* Breach and attack simulation (BAS) software is used to mimic real-world security threats to help businesses prepare incident response plans and discover potential vulnerabilities in their security systems. These simulated attacks might send fake phishing attacks to employees or attempt a cyberattack on a company’s [web application firewall](https://www.g2.com/categories/web-application-firewall-waf). Many tools even provide automated simulations with AI-based threat logic and continuous testing to ensure teams are always prepared to properly handle security incidents. Most of these simulations are available at all times. Many businesses use them periodically as updates are made to security systems or security policies are changed. Without simulated attacks, it can be difficult to assess the efficacy of security operations; customized simulations can mimic various threats to different surface areas or within unique environments to help businesses prepare and evaluate their defense against all kinds of multivector threats. Breach and attack simulation software tools are typically capable of performing [penetration tests](https://www.g2.com/categories/penetration-testing) or simulate attacks similar to some [dynamic application security testing](https://www.g2.com/categories/dynamic-application-security-testing-dast) tools and [vulnerability scanners](https://www.g2.com/categories/vulnerability-scanner). But most of those solutions only mimic a single kind of threat and are not continuously available. They also do not provide the same outcome details and report on vulnerabilities and security posture to the same degree of BAS solutions. To qualify for inclusion in the Breach and Attack Simulation (BAS) software category, a product must: - Deploy threats targeting various attack surfaces - Simulate both cyberattacks and data breaches - Quantify risk and evaluate security posture based on attack response - Provide remediation process guidance and improvement suggestions ## How Many Breach and Attack Simulation (BAS) Software Products Does G2 Track? **Total Products under this Category:** 53 ### Category Stats (May 2026) - **Average Rating**: 4.55/5 (↑0.04 vs Apr 2026) - **New Reviews This Quarter**: 24 - **Buyer Segments**: Enterprise 39% │ Small-Business 35% │ Mid-Market 26% - **Top Trending Product**: Right-Hand Cybersecurity (+0.003) *Last updated: May 18, 2026* ## How Does G2 Rank Breach and Attack Simulation (BAS) Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 1,200+ Authentic Reviews - 53+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals.
