External penetration test
We breach your internet-facing perimeter the way a remote attacker would, then pivot toward your crown jewels.
Offensive Security
We attack you before the adversary does
Methodology-driven penetration testing and full-scope red-team operations that expose the exact paths a real attacker would take — across your perimeter, applications, cloud, and people — then show you precisely how to close them.
Overview
Real adversary tradecraft, on your side
Automated scanners find the easy stuff. Our testers think like attackers — chaining low-severity findings into full compromise the way a real intruder would.
A vulnerability scan tells you what's broken. A S-Security penetration test tells you what an attacker can actually do with it — and what it would cost your business.
Our consultants hold OSCP, OSWE, GXPN, and CRTO certifications and have breached banks, hospitals, SaaS platforms, and industrial environments. Every engagement is manual-led, scoped to your real risk, and mapped to MITRE ATT&CK so you can see exactly which adversary techniques succeed against you today.
- External network — internet-facing exposure, perimeter breach, and pivot.
- Internal network — assumed-breach, privilege escalation, domain dominance.
- Web & API — OWASP Top 10, business-logic abuse, auth bypass.
- Cloud — AWS, Azure, and GCP misconfig and identity attack paths.
- Social engineering — phishing, vishing, and physical access.
- Red team — objective-based, full-scope, against your live defenses.
What's included
Engagement types we run
Pick a single assessment or a layered program — every test is manual-led and evidence-backed.
Internal / assumed breach
Starting from a single foothold, we escalate privileges and chase domain dominance to show how far a breach really spreads.
Web & API testing
Deep manual testing for injection, broken auth, IDOR, and business-logic flaws scanners never catch.
Cloud penetration test
IAM privilege escalation, exposed storage, and metadata abuse across AWS, Azure, and GCP.
Social engineering
Targeted phishing, vishing, and physical intrusion tests that measure your true human attack surface.
Full red team
Objective-based, stealthy operations against your live defenses to test detection and response, not just controls.
Methodology
Rigorous, repeatable, evidence-backed
Aligned to OSSTMM, PTES, OWASP, and NIST 800-115 — and mapped to MITRE ATT&CK throughout.
Scoping & rules of engagement
We define targets, objectives, timing, and safety boundaries together — so the test reflects your real risk without disrupting production.
Reconnaissance & mapping
OSINT and active discovery build a complete picture of your attack surface, just as a determined adversary would.
Exploitation & chaining
Manual exploitation chains findings into realistic attack paths, validating impact rather than reporting theoretical risk.
Post-exploitation
Privilege escalation, lateral movement, and data-access testing show exactly how deep a breach could go.
Reporting & retest
A prioritized, plain-English report with reproduction steps — plus a complimentary retest once you've remediated.

Deliverables
What you walk away with
Executive & technical report
A board-ready summary of business risk plus a detailed technical write-up with reproduction steps and remediation guidance.
Attack-path narratives
Step-by-step kill chains mapped to MITRE ATT&CK, so your defenders know exactly which techniques to detect.
Remediation debrief & retest
A live readout with your team and a complimentary retest to confirm fixes actually held — at no extra cost.
Why S-Security for pen testing
The difference between a checkbox and a real test
Senior testers, every time
No junior hand-offs. The certified consultant who scopes your engagement is the one breaking into your systems.
Impact, not noise
We prioritize by what an attacker can actually achieve — so you fix the findings that matter, not a 300-page scanner dump.
Retest included
Every engagement includes a free retest window, because a finding isn't closed until we've proven the fix works.
"Their red team reached domain admin in two days using a path our last three vendors swore was impossible. The report was the clearest remediation roadmap we've ever received."

FAQ
Pen testing questions, answered
What's the difference between a pen test and a red team?
A penetration test thoroughly assesses a defined scope (an app, a network, your cloud) to find as many exploitable issues as possible. A red team is objective-based and stealthy — it simulates a specific adversary chasing a goal against your live defenses to test whether your detection and response actually work.
Will testing disrupt our production systems?
No. We agree clear rules of engagement up front, avoid destructive techniques on production unless you explicitly request them, and maintain a real-time channel so any sensitive action can be paused instantly.
How often should we test?
At least annually, and after any major change — a new application, cloud migration, or merger. Many clients also run continuous testing programs to keep pace with frequent releases. Compliance frameworks like PCI DSS mandate at least yearly testing.
Is a retest really included?
Yes. Every engagement includes a complimentary retest within 30 days so we can verify your remediations held and issue an updated report — useful proof for auditors, customers, and your board.
