What Are the 7 Low-Cost Steps US Companies Can Take to Secure Credentials for NIS2?

Stolen or weak credentials remain one of the most common ways attackers get into a business, and NIS2 puts that risk on the board's agenda. For US firms with EU customers or subsidiaries, NIS2 can matter even though it is not a US law. The good news: seven low-cost steps cover most of the practical ground.

What is the Concept

NIS2 is the European Union's updated network and information security directive. It widens the list of sectors covered and expects organisations to manage cyber risk, including access control and authentication, with named management accountability. NIS2 is EU law, so US companies are usually affected indirectly: through EU subsidiaries, or as suppliers to EU entities that must pass security expectations down their supply chain. Check with counsel whether you are in scope.

We frame the response as the Credential Hygiene Seven: a short list of controls that protect logins first, because logins are where a small team gets the most protection per dollar spent. This is general guidance, not legal advice; confirm your obligations with counsel.

Why It Matters Now (2025–2026 Context)

US SMEs in New York, Austin, San Francisco or Chicago that sell to European customers increasingly meet NIS2-driven security questionnaires. Domestic frameworks such as NIST guidance and state breach laws point the same direction, so one set of credential controls serves several audiences.

The contrarian view: compliance paperwork does not stop breaches, and an expensive tool does not either. Most SME incidents trace back to reused passwords, missing multi-factor authentication or an ex-employee account nobody closed.

How AI Is Changing This

Attackers use AI to write convincing phishing emails and to test leaked passwords at scale, so older warning signs such as bad grammar no longer help. Defenders can use the same technology: modern identity platforms flag impossible-travel logins and unusual access patterns automatically.

A strong opinion: phishing-resistant authentication, such as passkeys or hardware security keys, is a better use of a small budget than yet another awareness video.

Real-World Examples

A realistic scenario: a Texas SaaS vendor loses a German prospect at the final stage because it cannot show multi-factor authentication on admin accounts. Enabling it took an afternoon and no new spend.

A realistic scenario: a 40-person services firm discovers a former contractor's account still active months after their contract ended. One quarterly access review would have closed it at no software cost.

Practical Insights / Actions

The seven steps, in order of effort versus payoff:

• Turn on multi-factor authentication for email, finance and admin accounts first.
• Adopt a business password manager and ban shared spreadsheets of passwords.
• Move privileged users to passkeys or hardware security keys.
• Remove default and shared admin accounts; give each person a named login.
• Run a quarterly access review and disable leavers the same day.
• Enable login alerts and log retention for your identity provider.
• Write a one-page credential incident plan and rehearse it once a year.

The founder mistake is buying monitoring software before fixing basics. The hidden opportunity is that clean credential controls also shorten customer security questionnaires, which helps win enterprise deals.

Future Outlook

Supply-chain security clauses are likely to keep flowing from EU buyers to US suppliers, making credential evidence a standard sales asset.

Expect customers and insurers to ask for evidence of multi-factor authentication and access reviews as routine, so building the habit now avoids a rushed scramble later.

Conclusion

Securing credentials is the cheapest meaningful step towards NIS2-style readiness. Start with multi-factor authentication and a password manager this week, then work down the list and document each control as you go.
