Imagine a bridge built without stress testing, where engineers only check for cracks after construction. When flaws inevitably appear, they scramble to patch weak spots until the subsequent failure forces another round of inspections.
This is how most companies still approach pentesting: periodic assessments, reactive fixes, and security are treated as unwelcome checkpoints. Engineering teams view pentesting as a necessary disruption, security teams struggle to keep up with growing attack surfaces, and vulnerabilities remain unaddressed between tests.
This cycle isn’t just inefficient but an open invitation for breaches. With over 2.8M+ new vulnerabilities in 2024 alone, security can no longer be a siloed function but a continuous function with pentesting as an engineering discipline embedded within development workflows.
Why is Pentesting Still Stuck in a Legacy Mindset?
Security as Tradition, Not Innovation
Pentesting was built for an era of monolithic software. Back then, applications changed rarely, and periodic testing made sense. Today, software is fluid—constantly updated, patched, and reconfigured. Security must evolve similarly, shifting from static audits to continuous, automated adversarial testing.
Unfortunately, in modern distributed systems, risks don’t emerge in isolation; they stem from interdependencies, integrations, and constant change. Security testing in engineering needs to mirror this complexity, embedding itself within the development workflow rather than existing as a separate audit function.
The One-and-Done Mentality
Attackers don’t wait for annual security tests. Every new deployment introduces fresh risks, yet many engineering teams still treat pentests as standalone events. This isn’t just outdated; it’s dangerous. Security must shift from an exercise in pentesting frameworks for engineers to a continuous, integrated process that evolves alongside development.
A yearly red teaming vs. blue teaming test only catches what is wrong at a single moment. By the time findings are addressed, new vulnerabilities have already surfaced. This lag creates a false sense of security, where teams believe they are protected when, in reality, they are perpetually playing catch-up.
Security Teams Are Thinking Like Auditors, Not Engineers
Most security teams assess risk the way an insurance company does, i.e., by identifying potential hazards, calculating impact, and documenting exposure. However, risk assessment alone doesn’t make a system secure. Attackers don’t care about risk scores; they care about what breaks when pressure is applied.
Security should be treated like performance engineering, where the goal isn’t just identifying bottlenecks but also stress-testing systems to the point of failure. As SREs use chaos engineering to simulate outages, security teams should simulate actual adversarial conditions. A resilient system isn’t one that simply passes a pentest but fails gracefully under attack and recovers without catastrophe.

The Case for Treating Pentesting as an Engineering Discipline
Security is a Design Problem
Engineers don’t “add” reliability to a system; they design for it. Security should follow the same principle. When security is treated as a design constraint, like performance or scalability, it forces trade-offs early, reducing the need for compensatory controls later.
This prevents the typical cycle of rushed security fixes that degrade user experience, slow down releases, and create long-term technical debt.
Choose Iteration Over Inspection
No engineering discipline thrives on static testing alone: software quality, scalability, and reliability are refined through iteration. Security remains one of the last holdouts of episodic testing, where pentests happen once or twice a year.
Shifting to a cybersecurity engineering model would integrate security validation into CI/CD, ensuring vulnerabilities are caught and fixed in real-time before they compound into systemic risks.
Adopting Engineering-Grade Metrics
Engineers don’t rely on arbitrary scores to measure performance; they use real-world metrics. Yet, security often defaults to CVSS scores that, more often than not, lack business acumen and contextual system perspectives.
A critical-rated bug in an isolated environment isn’t the same as a lower severity issue that enables privilege escalation. Security assessments must evolve toward risk-based models, integrating exploitability, impact, and mitigation feasibility into decision-making.
| Aspect | Traditional Pentesting | Pentesting as Engineering |
|---|---|---|
| Testing Frequency | Periodic (e.g., once or twice a year) | Continuous, integrated within CI/CD |
| Approach | One-time check, reactive fixes after the fact | Proactive, real-time vulnerability identification |
| Security Role | Separate, after-the-fact process | Embedded within development workflows |
| Risk Exposure | High between tests, vulnerability gaps emerge | Lower risk, vulnerabilities fixed in real-time |
| Team Collaboration | The security team isolated, with little interaction | Cross-functional collaboration, security as a shared responsibility |
| Goal | Compliance and audits | Resilience and failure tolerance |
| Focus | Identifying known vulnerabilities at a specific point | Stress-testing systems, simulating real-world attacks |
Security Engineering in Practice
Security today is treated as an afterthought—something to be audited, approved, or fixed in response to incidents. Pentesting as an engineering discipline, instead of laser focusing on compliance and firefighting, would be a continuous, measurable function woven into how systems evolve.
A security-first engineering mindset would take site reliability engineering (SRE) cues. Instead of assuming defenses will hold, teams would plan for failure, continuously measuring security drift, validating assumptions, and stress-testing systems under real-world conditions.
Simply put, security would evolve from minimizing loss to ensuring predictable, controlled outcomes when things go wrong, redefining how organizations handle security debt. Just as technical debt slows innovation, unaddressed security gaps compound over time, creating unseen risks that surface at the worst possible moments.
For example, a pentesting as an engineering approach would treat security debt as a live metric tracked, prioritized, and resolved with the same urgency as performance and scalability bottlenecks. Thus, as a discipline of software engineering, pentesting would:
- Operate like SRE, continuously tested and improved, not just audited.
- Treat security debt as a constraint, reducing risk accumulation over time.
- Engineer for failure, ensuring that breaches are predictable and containable.
No other pentest product combines automated scanning + expert guidance like we do.

Rethinking the Role of the CISO and Security Teams
From Gatekeepers to Enablers
Security has traditionally been seen as a final checkpoint—a necessary but often obstructive step before release. This approach no longer scales in environments where rapid development and continuous delivery are the norm. Security must transition from a control function to an integrated enabler, helping teams ship fast while staying secure.
- Make security frictionless: Invest in security solutions that integrate directly into developer workflows, from IDE plugins to automated code reviews.
- Shift security left, but with support: Provide developers with actionable security insights rather than just alerts, enabling them to fix issues early.
- Encourage security ownership across teams: Move from a security-as-a-service model to security-as-a-shared responsibility, with engineering teams empowered to make security-conscious decisions.
Security Engineers, Not Just Security Analysts
Traditional security teams have often operated in isolation, focusing on finding vulnerabilities rather than fixing them. This must change. Security professionals must be builders—able to write secure code, automate defenses, and contribute directly to engineering solutions rather than simply flagging risks.
- Hire for engineering expertise in security roles: Prioritize security hires with coding and automation skills who can contribute to development processes.
- Embed security engineers within product teams: Move security practitioners closer to development, ensuring security is considered at every stage of the build process.
- Develop internal security champions: Train developers in security best practices to act as their teams’ first line of defense.
Budgeting for Engineering, Not Just Tools
Security budgets have traditionally focused on buying more tools—scanners, firewalls, monitoring platforms—while engineering investments have remained secondary. The problem? Tools generate insights, but engineers turn those insights into fixes. Without engineering investment, security debt accumulates.
- Rebalance budgets to prioritize security engineering: Ensure funding goes toward automation, developer training, and security-focused engineering initiatives.
- Invest in automation over manual triage: Focus on security engineering frameworks and tools that reduce manual effort by automatically remediating common CVEs.
- Make security a performance metric for engineering teams: Incorporate security outcomes into development KPIs, ensuring secure code is a key expectation.
