Secure Code Review

Why it matters

Some of the most serious vulnerabilities are invisible from the outside but obvious in the source — subtle authorization logic, unsafe deserialization and injection sinks that a black-box test can only sample. Reviewing the code finds the root cause and often an entire class of related bugs at once.

Pairing experienced application-security engineers with SAST tooling gives developers precise, in-context fixes, making secure code review one of the highest-leverage investments in an application security program.

What we test

• Taint & data-flow analysis
• Injection and unsafe deserialization
• Authentication & authorization logic flaws
• Hardcoded secrets & credential exposure
• Insecure cryptography & dependency risk
• Framework-specific insecure patterns

Common vulnerabilities we uncover

• Injection and unsafe deserialization sinks
• Broken authentication and authorization logic
• Hardcoded secrets and credential exposure
• Insecure cryptography and randomness
• Vulnerable and outdated dependencies
• Framework-specific insecure patterns

Our methodology

1. Scoping & rules of engagement. We agree objectives, targets and boundaries for your secure code review, so testing is safe, authorized and focused on what matters to your business.
2. Reconnaissance & mapping. We enumerate the full attack surface in scope, building a complete picture before any exploitation begins.
3. Manual exploitation. Our senior testers chain vulnerabilities by hand — going far beyond automated scanners — to prove real, demonstrable impact.
4. Analysis & reporting. Every finding is triaged, risk-rated with CVSS and written up with a copy-paste reproduction and clear remediation.
5. Remediation support & free retest. We support your team through the fixes and retest the remediated issues to confirm they are genuinely closed.

Tools & techniques

We combine manual review by senior application-security engineers with SAST tooling such as Semgrep and CodeQL, plus software-composition analysis for dependencies. We trace untrusted data from source to sink, validate tool findings to remove false positives, and identify logic and design flaws that automated analysis cannot understand. Findings are mapped to file and line with secure-pattern fixes.

When you need this engagement

• For high-risk components handling auth, payments or crypto
• Before a major release or third-party security audit
• When a black-box pentest suggests deeper logic flaws
• To harden a codebase against entire vulnerability classes

What you receive

• Findings mapped to file and line
• Root-cause analysis and secure-pattern fixes
• Risk ratings and prioritized backlog
• Developer walkthrough session

What’s included in your report

Every secure code review engagement concludes with a comprehensive, board-ready report and a working session to walk your team through it. Your report includes:

• An executive summary with overall risk posture for non-technical stakeholders
• Detailed technical findings, each with a step-by-step, copy-paste reproduction
• CVSS v3.1 severity ratings and business-impact context for every issue
• Prioritized, actionable remediation guidance your engineers can apply directly
• A complimentary retest to confirm fixes and update finding status
• A formal attestation letter for customers, auditors and compliance programs

Standards & frameworks

Outcomes you can expect

After your secure code review, you will have clear, evidence-based visibility into your real security risk — not a scanner’s guesswork. You will know exactly which weaknesses an attacker could exploit, what the business impact would be, and the precise steps to fix them in priority order. Teams use our findings to close critical gaps, satisfy customer and regulator security requirements, and demonstrate due diligence to their board. With a complimentary retest included, you also get documented proof that the issues are genuinely resolved.

Engagement details & logistics

Every secure code review starts with a short, no-obligation scoping call to understand your goals, environment and constraints, followed by a fixed-price proposal and a clear statement of work. Most engagements are delivered fully remotely, with on-site work arranged where it genuinely adds value. Throughout testing we maintain an agreed communication cadence and escalate any critical, high-impact finding to you immediately rather than waiting for the final report. All work is performed under a signed NDA with strict data-handling controls, using safe, non-disruptive techniques and carefully coordinated rules of engagement to protect your production systems. On completion you receive your report and a walkthrough session, followed by a complimentary retest once your fixes are in place. Typical engagements are booked one to three weeks in advance, and urgent or pre-deadline testing can often be accommodated — just ask at hi@agentoffense.com.

Why organizations choose AgentOffense

Our secure code review is delivered by senior offensive-security engineers who test the way real attackers do — manually, creatively and with a relentless focus on proving genuine, demonstrable impact. Here is what sets our engagements apart:

• Manual, exploit-driven testing that chains vulnerabilities the way a real attacker would, going far beyond what automated scanners can find.
• Reproducible proof for every finding, with copy-paste reproduction steps your engineers can follow and independently verify.
• Honest severity calibration so you invest in fixing what genuinely matters and avoid wasting effort on false positives and noise.
• Clear, business-focused reporting that speaks to engineers and executives alike, tying every issue to real-world impact.
• A complimentary retest included, so you get documented proof that your fixes actually close the attack path.
• Responsible, collaborative delivery with a named point of contact and secure handling of all data throughout the engagement.

How much does Secure Code Review cost?

Every secure code review is scoped and priced individually, so you pay for exactly the coverage you need — with no hidden extras. After a short, no-obligation scoping call we send a fixed-price quote, usually within one business day, with clear deliverables, a firm timeline and a complimentary retest included. The price of your secure code review depends on the size and complexity of the target and the depth of testing required, so you always know the cost up front before any work begins.
