Our Approach to Application Pentesting

Two hands holding a phone

Full-Scope Application Security

No surface left unchecked, no gap ignored.

Starting with a keen understanding of potential threats, our threat modeling process methodically identifies, categorizes, and prioritizes vulnerabilities across every attack surface. We adapt the OWASP Web Security Testing Guide (WSTG) with years of practical experience to ensure comprehensive coverage, from authentication flows and business logic to APIs, mobile back ends, and cloud integrations.

Having tested hundreds of applications from in-house developed systems to Silicon Valley SaaS offerings, we have seen it all and understand how to target each environment differently. Whether we have access to source code for Static Application Security Testing (SAST) or perform Dynamic Application Security Testing (DAST) against live applications, our methodology is designed to uncover risks wherever they reside. This broad approach provides visibility into how attackers could target multiple surfaces, giving your team confidence that no entry point is overlooked.

Expertise Beyond Surface-Level Checks

Dissecting applications to uncover what others miss

Our team goes beyond surface-level scanning to perform a full, manual deep dive into your applications. We test for vulnerabilities such as authentication flaws, logic bypasses, API misconfigurations, request smuggling, injection attacks, privilege escalation, and more using the same adversarial mindset attackers would.

Every finding is validated, documented with evidence, and prioritized by real risk. With expertise rooted in both offensive security and defensive understanding, we deliver results that not only expose vulnerabilities but also guide your team in strengthening applications against future attacks.

Our AI Pentesting Playbook

Map System Inputs

We identify and catalog every input path including UIs, APIs, file uploads, integrations, and agent interactions. This defines how untrusted data reaches the model and highlights where injection risks exist.

Ecosystem Fingerprinting

We identify and catalog every input path including UIs, APIs, file uploads, integrations, and agent interactions. This defines how untrusted data reaches the model and highlights where injection risks exist.

Attack the Model

We evaluate the AI model for jailbreaks, safety filter bypasses, poisoning risks, inversion attacks, and configuration flaws. This ensures vulnerabilities beyond content generation are discovered and validated.

04

Attack the Prompt

We apply advanced prompting tactics such as context manipulation, chained instructions, hidden directives, and agent poisoning. These techniques measure how the system interprets and executes instructions under pressure.

Attack the Data

We examine training data, embeddings, and RAG pipelines for leakage, corruption, or manipulation. This identifies how poisoned or tainted data can compromise AI reliability and trustworthiness.

06

Application Testing

We review AI-enabled applications and integrations for traditional web security issues such as SSRF, XSS, command injection, IDOR, and insecure output handling. This ensures both classic and AI-specific vulnerabilities are addressed.

Exploit Chaining

We simulate real adversaries by chaining vulnerabilities, escalating privileges, and pivoting across SaaS, cloud, and on-prem environments. This validates the business impact of compromise beyond the initial AI layer.

Frequently Asked Application Security Questions

Answers to Your Questions

Do you test AI and LLM systems?

Yes. We provide penetration testing specifically for AI and LLM-powered applications. This includes testing for prompt injection, data leakage, model manipulation, and integration risks that traditional security assessments often miss. As AI adoption grows, specialized pentesting ensures your models and workflows remain secure and compliant.

How fast can I get a pentest?

We typically are able to schedule out within 5-10 days from a scoping call.

How much does a penetration test cost?

Pricing depends on scope and depth. Smaller, targeted assessments may start in the low five figures, while enterprise engagements scale accordingly. Factors include number of applications, network size, complexity of integrations, and whether specialized testing (e.g., AI or red team) is required.. Please reach out to us for a detailed quote. We respond to inquiries same day!

What deliverables will we receive?

You’ll receive full access to our PTaaS portal with real-time findings, remediation tracking, and retest requests. At the end of the engagement, we deliver a technical report with detailed vulnerabilities, proof of exploitation, and remediation guidance, plus an executive summary for leadership and compliance.

How do you handle compliance requirements like SOC 2 or PCI DSS?

We map penetration testing results to compliance frameworks such as SOC 2, PCI DSS, HIPAA, and ISO 27001. Our reports provide the evidence auditors and regulators require, and we can align testing frequency to your compliance cycles.

How do you scope a penetration test?

Scoping is based on the size, complexity, and business criticality of the systems in scope. We work with your team to understand applications, networks, cloud assets, or APIs, then define the depth of testing required. This ensures testing reflects real-world risk paths, not just surface-level scans.

What training does Redline provide?

Redline provides a full spectrum of cybersecurity training options. We host live webinars to share industry insights, deliver hands-on workshops for teams, and release on-demand training modules and labs that can be accessed anytime. For more interactive learning, we organize Capture the Flag (CTF) events where participants apply skills in real-world attack and defense scenarios. Whether your goal is awareness, technical depth, or team-building, our training programs are designed to strengthen skills and improve resilience.

How long does a penetration test take?

Most one-time tests are completed in 1–3 weeks depending on scope. PTaaS clients benefit from continuous testing with real-time findings. We align timelines to your needs, whether you require a fast turnaround or an in-depth, phased approach.

Do you offer retesting after remediation?

Yes. Retesting is included in most engagements by default. Retesting ensures vulnerabilities have been fixed correctly and provides closure for compliance and internal risk reporting.

What makes Redline different from other firms?

Redline is built by real hackers, not check-box auditors. Our team has published CVEs, climbed bug bounty leaderboards, and contributed to the security community for over a decade! We combine technical expertise with a clear reporting process that provides both deep technical insight and executive-ready summaries.
