Getting fit requires three things: a goal, a plan, and action. When you put in the work, you get results. There are no shortcuts. If a new solution promises big results with little effort, it’s likely too good to be true. These shortcuts often come with hidden costs. People who achieve lasting results understand this—and they embrace the process.
This same mindset applies to today’s security landscape.
The Rise of Automated Security Testing
We’re seeing more organizations adopt automated tools to test their environments and applications. These tools promise faster, cheaper results by attempting to mimic manual penetration testing. They’re designed to lower the expertise barrier—but this convenience comes at a cost.
The Upside of Automation
Yes, there are benefits:
- Continuous assessments: Automated tools can run 24/7, flagging new issues quickly and efficiently.
- Control validation: They help monitor for unexpected changes or new risks.
- Real-time feedback: Agent-based solutions now offer rapid insights.
We’ve long supported continuous vulnerability scanning, and automation plays a valuable role here.
But Not All Testing Is Equal
It’s critical to understand the limitations of automated testing. Not all penetration tests are created equal. At CTInfoSec, we’ve been conducting pentests for nearly 2 decades. We use a wide range of tools—some highly specialized, others more general. Just like targeted exercises build specific muscles, different tools are needed to assess different assets.
Where Automation Falls Short
Automation can’t replace human expertise. Knowing when to use a tool, how to interpret a result, and the next steps to take are the areas where humans cannot be replaced with automation. There will be potentially significant risks left unidentified through automation. Here’s why:
- Sensitive data leakage: Tools may miss metadata leaks that expose credentials (OWASP example).
- Business logic flaws: Broken business logic not tested that discloses privileged data (OWASP example).
- Technique chaining: Tools unable to combine simple techniques like user enumeration and password stuffing to understand real risk (Rapid7 example).
These are just a few examples of common gaps in automated testing—there are many more.
The Bottom Line
Automated testing is a valuable tool, but it’s not a complete solution.
- Comprehensive coverage? Unlikely.
- Compliance-ready? That’s debatable—and best left to legal experts.
- Less effort, same results? No.
Security teams should use automation strategically, alongside manual testing, to get the best results.
