BAS 101: Why Even Regulated Industries Need BAS Solutions

A Cymulate customer recently asked:

"I'm in a regulated industry and do penetration testing once a year for compliance. Why would I also use Breach and Attack Simulation?"

This is a valid question, especially for organizations bound by strict regulatory frameworks. While annual penetration testing is a standard compliance measure, Breach and Attack Simulation (BAS) offers distinct and necessary advantages.

Annual Penetration Testing Is Not Enough

Penetration testing provides a snapshot in time. It focuses on a limited scope under controlled conditions, offering valuable but inherently restricted insights into your security posture. Because it’s typically performed once a year, it cannot reflect the ongoing changes in your environment or threat landscape.

Pen-testers often operate under Rules of Engagement (RoEs) that restrict the scope and aggressiveness of their tactics to avoid downtime or damage. These limitations can leave gaps undiagnosed—especially when some systems are off-limits. Penetration testing also tends to follow the quickest viable path to compromise, meaning alternative methods and additional vulnerabilities may be left unexplored.

Moreover, since pen-tests are almost always human-run, time constraints limit how many techniques can be applied. Once a tester finds a successful method, they often don’t try others, even though those might reveal additional risks.

BAS Fills the Gaps Left by Pen Testing

BAS platforms like Cymulate are designed for safe, continuous operation in production environments. They deconstruct complex attack techniques into safe-to-run components that won’t cause downtime or data loss. This enables the testing of thousands of methods and variations without the risks associated with full-scale pen testing.

Unlike human-led testing, BAS leverages automation to explore multiple pathways simultaneously, covering a broader attack surface. Because it’s automated and less restricted by RoEs, BAS can run more frequently and thoroughly, identifying vulnerabilities that annual testing alone would likely miss.

You’re not just getting more frequent testing—you’re getting deeper testing that aligns with how attackers actually operate.

When Regulatory Reports Become Public

Many organizations assume their compliance-related pen test results are confidential. But that’s not always the case. Take HIPAA, for example. While reports submitted to the U.S. Department of Health and Human Services are generally confidential, they can be disclosed if a Freedom of Information Act (FoIA) request is granted.

This means internal vulnerabilities discovered during pen testing could become public knowledge, damaging your organization’s reputation and exposing it to potential attacks. The same risk exists if these reports are used in legal proceedings and not sealed by the court.

With BAS, you can identify and fix gaps continuously throughout the year—long before an official pen test. This ensures that, if your compliance report ever becomes public, it reflects a well-secured environment that’s actively managed and monitored.

Improving Regulatory Test Results with BAS

BAS empowers your IT and cybersecurity teams to stay ahead of threats by offering updated testing on a regular schedule—weekly or monthly. This ongoing assessment leads to continuous remediation, reducing the likelihood that a regulatory pen test will uncover major issues.

When the official pen test does occur, auditors are more likely to find a mature security posture that demonstrates your organization’s proactive approach. Even if a report becomes public, it will show that you’ve taken appropriate steps to protect sensitive data and systems.

Conclusion: BAS and Pen Testing Are Better Together

Annual pen testing is a critical compliance tool—but it’s not sufficient on its own. Breach and Attack Simulation adds the continuous coverage, depth, and automation necessary to maintain strong security year-round.

Together, these approaches form a robust security validation strategy. Pen testing provides official compliance documentation, while BAS ensures that documentation reflects real, ongoing protection.

If you're ready to move beyond one-and-done testing, a BAS platform like Cymulate ensures you're always one step ahead - of both attackers and auditors.
