Held by our operators — the certifications behind the hands-on work.
Full-spectrum offensive security
From a single web app to your entire stack — engaged individually or as an ongoing partnership.
No scanners on autopilot.
We run lean, senior engagements built around how your team actually ships — and hand back findings you can act on the same week.
Senior operators only
Every engagement is run by experienced testers — never juniors or tooling left on its own.
Manual-first method
Tooling assists; humans find the business-logic bugs that scanners walk straight past.
Built for startup speed
Scoped in days, not months, and paced to your release cycle instead of fighting it.
Reports you can act on
Prioritized findings, reproducible proof, and remediation support — then we retest.
AI does the grunt work.
Humans do the hunting.
We build AI agents and workflows into every engagement — to map attack surface, triage noise, and draft findings faster. That frees our operators to spend their hours on the creative, adversarial thinking machines still can't do.
How an engagement runs
Define the target
We agree objectives, assets, and rules of engagement up front — no surprises.
Hands-on testing
Senior operators attack the system manually, with you looped in throughout.
Clear findings
Prioritized issues with proof, impact, and concrete remediation steps.
Confirm the fix
Once you've remediated, we verify each finding is genuinely closed.
Common questions
What does Aethersec do?
Aethersec is a boutique offensive-security firm. We provide manual penetration testing, red and purple teaming, hardware hacking, and blockchain & web3 security for startups and tech teams — attacking your applications, infrastructure, and hardware the way a real adversary would.
What is penetration testing?
Penetration testing is a controlled, hands-on security assessment where senior operators attack your systems the way a real adversary would, to find exploitable weaknesses before attackers do. We test web apps, APIs, networks, cloud, and mobile with a manual-first approach — tooling assists, but humans find the business-logic flaws scanners miss.
Do you offer blockchain and web3 security testing?
Yes — it's our Blockchain and Web3 Infrastructure Security service. We secure the off-chain attack surface around blockchain and web3 products: wallet architecture, custody, key management, APIs, and infrastructure — where most real-world crypto losses actually happen. We don't perform on-chain smart-contract audits.
