SECURITY OPERATIONS

Protect. Detect.
Build Cyber Resilience.

Offensive security, compliance and training for organizations that take risk seriously. We uncover exploitable weaknesses, meet compliance obligations and turn every finding into stronger defense.

// 01 — WHAT WE DO

An end-to-end security offering across offense, defense & governance

Manual expert testing combined with automated tooling — every engagement ends in proof-of-concept evidence, business impact and a prioritized remediation plan. We don't just hand you a list of vulnerabilities; we show how an attacker would chain them, what it means for your business, and exactly how to close the gap. From a single web application to a full multi-cloud estate, our work maps to OWASP, NIST 800-115, PTES, ISO 27001 and MITRE ATT&CK so your findings are credible with auditors, regulators and your board.

RECON

Find it first

We attack like a real adversary — down to the protocol and circuit level — before someone else does.

SURFACE

Across your estate

Network, cloud, mobile, containers and Kubernetes — wherever your workloads run.

DEFENSE

Turn data into defense

Every finding becomes detection, response and hardening that compounds over time.

// 02 — WHY GMGSEC

A practical partner for stronger security

GMGSec works with organizations that treat cyber risk as a business risk — banks and fintechs, software companies, critical infrastructure and the public sector. We pair deep offensive skill with a defender's mindset, so every engagement leaves your team measurably harder to breach and better prepared to respond.

Proven, hands-on expertise

Deep, hands-on skills across offensive security, compliance and training — not just scanners.

Real-world realism

Simulations that reveal real exposure and business impact, the way an actual adversary would.

Framework-aligned

OWASP, NIST, PTES, ISO 27001 and MITRE ATT&CK with clear, prioritized remediation.

Purple-team mindset

Every finding becomes detection, response and hardening that compounds over time.

// 03 — HOW WE WORK

From scope to lasting improvement

A clear, repeatable engagement model with no surprises. We agree on objectives and rules of engagement up front, test against real-world attack chains, report in language both engineers and executives can act on, and validate the fixes — turning a point-in-time assessment into a cycle of continuous hardening.

  1. 1

    Scope

    Define objectives, targets and rules of engagement together.

  2. 2

    Assess

    Manual and automated testing against real attack chains.

  3. 3

    Report

    Executive summary, technical evidence and prioritized fixes.

  4. 4

    Improve

    Retest, validate and harden — turning findings into resilience.

// 04 — ENGAGEMENT MODELS

Choose the level of attacker knowledge

Every assessment is scoped to your risk, budget and timeline. We run engagements across the full spectrum of attacker knowledge — from a blind external adversary with nothing to go on, to a fully briefed review of your source code and architecture — so you get the depth of coverage that matters most to your business. Not sure which fits? We'll recommend the right model after a short scoping call.

Black box

We start with zero inside knowledge, exactly like a real external attacker. Best for testing your perimeter, internet exposure and detection from the outside in.

Gray box

You share limited context — a standard user account, documentation or partial architecture. The most cost-effective balance of realism and coverage for most applications and APIs.

White box

Full visibility into source code, configuration and design, working alongside your engineers. The deepest possible review, ideal for critical systems where nothing can be missed.

// 05 — STANDARDS

Aligned to the frameworks that matter

Our methodology maps to the standards your auditors, regulators and board already trust.

// 06 — FAQ

Questions teams ask before we start

Straight answers to the things clients want to know up front. If your question isn't here, reach out — we're happy to talk through scope, timing and cost with no obligation.

How long does a typical engagement take?

It depends on scope and the type of engagement — and we run the full range: web, mobile, internal/infrastructure, API, social engineering, reverse engineering and red-team operations. A focused single-target assessment is typically one to two weeks of active testing plus reporting, while broader work (internal networks, multi-cloud estates or goal-based red teaming) runs longer. We agree the exact window during scoping so there are no surprises on either side.

Will testing disrupt our production systems?

Safety is part of the rules of engagement. We tune intensity to your environment, test against staging where appropriate, and coordinate any potentially disruptive activity in advance. Destructive testing only ever happens with your explicit written approval.

What do we actually receive at the end?

An executive summary for leadership, detailed technical findings with proof-of-concept evidence, a risk-rated and prioritized remediation plan, and a retest to validate the fixes. Everything maps to the frameworks your auditors and board already recognize.

How do you handle our sensitive data?

All findings and evidence are handled under strict confidentiality, stored encrypted, and shared only through secure channels. We can sign your NDA before any work begins and securely destroy engagement data after the agreed retention period.

Can you help us fix what you find, not just report it?

Yes. We work as a purple-team partner — pairing with your engineers on remediation, tuning detections from real attack paths, and retesting until the risk is genuinely closed. The goal is lasting resilience, not a one-time list of problems.

// 07 — FREE SECURITY CHECKUP

Is your data exposed? Check in 30 seconds

Three instant checks against billions of breached records — by domain, email or password. Your password is never sent anywhere; only the first five characters of its hash leave your browser. No account, no tracking, nothing stored.

⏳ You get one free 5-minute session per visit — check as many of your own domains as you like during it. The countdown starts when you run your first check; after it ends there's a 24-hour cooldown.

Powered by open-source breach datasets, continuously updated. Your password is checked privately — only a short hash prefix is ever sent. GMGSec stores nothing you type here. For a full, authorized assessment of your systems, talk to our team.
