Authorised offensive security for fintech, crypto, and finance.

Defenders at money platforms need offence that is scoped — not theatre.

Exchanges, fintechs, and financial platforms face high-value, high-scrutiny threat models. Unscoped “red team” noise and tool spam don’t help. What helps is authorised offensive work with clear rules, clear targets, and findings your team can act on — plus a productised surface check when you want on-demand coverage between human engagements.

Authorised offence — defined.

nexis-offense.com is the offensive brand surface for Nexis: human-led authorised offensive security and managed review for fintech, crypto, and finance. It is not a separate shadow product line and not a promise of AI that attacks for you.

We do

• Authorised offensive engagements under a written Rules of Engagement / Letter of Authorisation
• Scoped testing on assets you prove you own and explicitly approve
• Findings your security and engineering leads can remediate
• Optional path into Nexis Scan on nexis-defence.com for on-demand authorised external checks between engagements

We do not

• Uncontrolled offence, third-party targeting, or “scan/hack anything”
• Claim “unhackable,” guaranteed secure, zero risk, or complete coverage
• Present automated Scan as a full penetration test or red-team certificate
• Claim continuous always-on offence or monitoring (not MVP)
• Claim AI that “hacks for you” or replaces human engagements
• Claim PCI/SOC2 certification by engagement or by Scan alone
• Claim kill-chain / blast-radius mapping unless a signed engagement explicitly delivers that scope

Offence and Scan — same company, clear split.

Need a point-in-time authorised external check on assets you own? Use Nexis Scan. Need human-led offensive work with a written RoE? Request an engagement here. Deeper analyzer capability is roadmap — labeled as such, not sold as shipped.

For teams that can’t afford vague offence.

Security and engineering leads at crypto exchanges, fintechs, and financial platforms who need authorised offensive clarity — scoped, documented, and honest about what was and wasn’t tested.
