Offensive Security That Exposes What Others Miss

Too many security assessments amount to little more than automated tool output dressed up in a PDF. At Pentestas, our engagements are hands-on, adversarial exercises conducted by experienced operators who discover hidden attack paths, exploit them in sequence, and quantify what your organization truly stands to lose. We find the gaps that technology alone cannot detect.

Six Specialized Penetration Testing Disciplines

Different environments demand distinct offensive strategies. We bring deep expertise to each one.

Web Application Security Testing

Deep-dive assessments targeting the OWASP Top 10, workflow manipulation, broken access controls, session handling weaknesses, and injection vectors. We approach your application the way a motivated adversary would - with patience and creativity.

Our Engagement Process From Start to Finish

A disciplined, five-stage framework that produces clear and actionable outcomes within two weeks.

Phase 1Day 1

Project Kickoff & Boundary Definition

We establish the engagement perimeter, testing goals, operational boundaries, and escalation procedures. Every stakeholder understands precisely which assets are in scope, which techniques will be employed, and where the lines are drawn. Zero guesswork.

Phase 2Days 2-3

Intelligence Gathering & Surface Mapping

Both passive and active intelligence collection to chart your full exposure. We identify subdomains, fingerprint technology stacks, locate undocumented interfaces, and assemble a thorough target inventory before launching any exploitation attempts.

Phase 3Days 4-8

Active Exploitation & Access Escalation

The heart of the assessment. We leverage identified weaknesses, combine them into multi-step attack sequences, elevate access rights, and traverse your infrastructure laterally - replicating the tactics a determined threat actor would deploy in the wild.

Phase 4Days 9-10

Impact Validation & Risk Demonstration

We quantify the genuine business consequences of every successful attack path. This includes documenting which sensitive records an intruder could exfiltrate, which critical systems they could commandeer, and what operational disruption they could inflict - backed by evidence your executives can grasp immediately.

Phase 5Days 11-14

Final Reporting & Guided Remediation

You receive a thorough deliverable featuring a leadership-ready executive overview, detailed technical write-ups with exploitation evidence, severity classifications, and prioritized fix recommendations. We present every finding to your team in a dedicated walkthrough session.

What Sets Pentestas Apart in Offensive Security

The critical differences between a rigorous penetration test and a repackaged vulnerability scan.

Human-Driven, Not Tool-Dependent

Every vulnerability we report is identified, confirmed, and exploited by an experienced operator. Tools accelerate our workflow but never replace critical thinking. Automated scanners consistently fail to catch logic errors, multi-step exploits, and the nuanced weaknesses that actually lead to breaches.

Experienced Operators Only

OSCP and OSEP credentialed professionals run every single engagement. We never bait-and-switch by pitching senior talent and delivering junior analysts. The consultant who designs your test plan is the same one executing it.

Firm Quotes Delivered in 24 Hours

You receive a precise cost figure before any work begins. No time-and-materials billing, no creeping scope charges, no end-of-project surprises. We define the engagement, set the price, and execute - exactly as promised.

Tied to Real Business Consequences

We go beyond cataloging technical weaknesses. We illustrate how each vulnerability translates into concrete organizational risk - which records are at stake, which systems face compromise, and what the financial fallout would be if an adversary exploited it first.

Complimentary Verification Retesting

Once your engineers have addressed our findings, we re-examine every reported vulnerability at zero additional cost. You walk away with a validated clean report proving that remediation was successful - not just an assumption that patches worked.

Completely Product-Neutral Advice

We do not resell security tools or earn referral fees. Our guidance is shaped exclusively by what benefits you - not a vendor partnership agreement. When we suggest a solution, it is because we believe it is the strongest fit, full stop.

Common Questions About Our Penetration Testing Services

How does a penetration test differ from running a vulnerability scanner?
A vulnerability scanner is automated software that flags known issues from a database. A penetration test is a human-led offensive exercise where a qualified professional actively exploits flaws, weaves them into realistic attack chains, escalates access, and proves tangible business consequences. Scanners catch surface-level problems; pen testers expose the hidden pathways that result in real-world breaches.
What is the investment for a penetration test?
Engagements start at $4,000 for a targeted API or network assessment. Web application testing begins at $5,000, mobile platforms at $6,000, and cloud environments at $5,000. We deliver a firm, fixed-price proposal within 24 hours - no time-and-materials billing or unexpected invoices.
What is the typical timeline for a penetration test?
Most projects take 10-14 business days from kickoff through final deliverables. The hands-on testing window generally spans 5-7 days, with the balance allocated to scoping, documentation, and remediation support.
Could a penetration test disrupt our production systems?
No. Our operators use carefully calibrated techniques engineered to identify weaknesses without inflicting damage. We formalize operational rules before any testing begins and maintain close coordination with your team to protect production availability. Across more than 600 completed engagements, we have maintained a flawless track record of zero unplanned outages.
What is the recommended frequency for penetration testing?
At least once per year, and following every major infrastructure change, product launch, or substantial code revision. Leading compliance standards (PCI DSS, SOC 2, ISO 27001) mandate yearly testing. Organizations facing heightened risk often choose quarterly cadences.
What deliverables are included with the engagement?
A thorough report containing a management-ready executive overview, granular technical write-ups with proof-of-concept evidence, severity ratings aligned to business impact, and step-by-step remediation instructions. We also hold a dedicated briefing session to review every finding with your team.
Is retesting available once we address the discovered issues?
Yes. Every engagement includes complimentary retesting at no extra cost. After your team applies the recommended fixes, we re-examine each finding to confirm the remediation is genuinely effective.
What qualifications do your security testers carry?
Our professionals hold OSCP, OSEP, CISSP, and CISA credentials. Every project is led by a seasoned consultant with years of practical offensive security experience - we never delegate client work to entry-level analysts.
