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. UK firms are outside the EU, but those serving EU customers still meet NIS2-driven expectations. 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 and does not apply directly in the UK, but UK firms with EU operations or EU clients may be covered or asked to meet its supply-chain expectations. UK guidance such as the NCSC advice and Cyber Essentials covers similar ground.
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 pound spent. This is general guidance, not legal advice; confirm your obligations with counsel.
Why It Matters Now (2025–2026 Context)
UK SMEs in London, Manchester, Birmingham or Edinburgh that supply EU businesses increasingly face NIS2-style questionnaires, while UK rules and the NCSC push in a similar direction. Credential controls satisfy both.
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 Manchester software house is asked by a Dutch client to prove multi-factor authentication and leaver processes. Because it already holds Cyber Essentials, it answers in a day instead of a fortnight.
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:
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. If you want an independent view, RP SoftTech offers a credential and access review as a starting consultation.
Future Outlook
UK legislation on cyber resilience is evolving, so firms that build credential controls now will adapt more easily to whichever requirements land.
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.
