7-5: Application Security Investment
Capital allocation strategies for SAST, DAST, penetration testing, and bug bounty programs.
🎯 What You'll Learn
- ✓ Calculate AppSec ROI
- ✓ Compare static vs dynamic tooling costs
- ✓ Design bug bounty economics
Static vs Dynamic Analysis (SAST/DAST)
Application Security (AppSec) tooling splits into two economic profiles: Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST).
SAST scans raw source code (Shift Left). It is cheap, fast, but highly prone to false positives, requiring heavy engineering labor to tune out noise. DAST scans the running application from the outside. It is slow, catches complex logic flaws, but has very low false positives.
The economic optimum is a hybrid model: heavy SAST running transparently in the CI/CD pipeline, backed by deep DAST scans prior to major version releases.
The engineering time wasted investigating SAST hits that are not real bugs.
How fast the tool completes. Slow scans block deployments and bleed money.
Review the alert configuration of your primary SAST tool (e.g., SonarQube, Snyk).

The Economics of Penetration Testing
A compliance-grade penetration test (Pen Test) costs $15k to $30k and provides a point-in-time snapshot. It is essentially a rapidly depreciating asset; the moment new code is pushed the next day, the test is outdated.
However, Pen Tests are mandatory for achieving SOC 2, closing enterprise deals, and satisfying cyber insurance underwriters. Therefore, a Pen Test is a compliance mandate first, and a security diagnostic second.
To maximize ROI from a Pen Test, force the consulting firm into "Purple Teaming" — where they actively collaborate with your internal defenders showing them *how* they breach the systems, rather than just throwing a PDF report over the wall.

Action Items
Why is a standard Penetration Test considered a "rapidly depreciating asset"?
Bug Bounty Mathematics
Bug Bounty programs (via HackerOne or Bugcrowd) crowdsource your security by paying independent researchers for finding exploits. You only pay for successful results, making it highly capital efficient compared to salaried penetration testers.
The economic catch: managing a public bug bounty requires dedicated triage engineers. If you launch a program without tuning out the noise, you will be crushed under thousands of worthless "low severity" submissions like missing email headers.
Private, invite-only bounties with highly targeted scopes yield the highest signal-to-noise ratio and the best ROI per dollar spent.
The volume of critical, actionable bugs vs worthless "beg bounty" spam submissions.
The internal engineering hours spent validating external bug submissions.
Design the scope for an initial, private Bug Bounty program.
