01 / Capabilities

Seven ways we get in.

Every engagement is scoped, rules-of-engagement signed, and run by the same engineers who build the exploits. No outsourcing, no scanners-as-a-service.

01
⊹

Penetration Testing / VAPT

Goal-driven testing across your apps, networks and cloud, mapped to OWASP, PTES and NIST. Findings ranked by real exploitability, not scanner noise.

02
✉

Phishing & Social Engineering

Realistic pretext campaigns over email, SMS, voice and physical access that measure how your people respond when an attacker comes knocking.

03
◎

Red Team Operations

Full-scope, objective-based adversary simulation against people, process and technology, run quietly against a live environment to test real detection.

04
⌬

Web & Mobile App Security

Deep manual testing of web, iOS and Android apps and their APIs, including auth, business logic and chained-vulnerability attack paths.

05
⊞

Network & Infrastructure

External and internal network pentests, Active Directory attack paths, segmentation and cloud configuration review from an attacker's seat.

02 / Methodology

The kill chain, run in reverse.

We follow the same path a real intruder would, documenting every step so your team can reproduce, detect and close it.

01

Recon

OSINT, attack-surface mapping and target profiling to find the seams before we touch a single system.

R
02

Exploit

Manual exploitation and custom tooling to gain a verified foothold, never just a theoretical CVE.

E
03

Pivot

Privilege escalation and lateral movement toward the assets that actually matter to your business.

P
04

Report

Clear, ranked, reproducible findings with proof, impact and a remediation path your engineers can act on.

R
05

Remediate

Re-testing, fix validation and a debrief with your blue team to make the next attacker's job far harder.

R
03 / Why Octasec

Built by operators,
not box-tickers.

  • 01

    Real adversary simulation

    We emulate the specific threat actors who target your sector, using the same tradecraft, not a generic checklist.

  • 02

    Manual-first, scanner-second

    Tools find the obvious. Our engineers find the chained, business-logic and human flaws that scanners never will.

  • 03

    Evidence you can act on

    Every finding ships with proof of exploitation, business impact and a concrete fix, ranked by exploitability.

  • 04

    Defenders left stronger

    We work alongside your blue team, sharing detections and hardening guidance so each engagement compounds.
