SME cybersecurity: the priorities to hold in 2026

NIS2, AI-powered phishing, 3-2-1 backups, MFA and passkeys: the cybersecurity priorities a Paris SME can no longer postpone in 2026.

Managed cybersecurity for a Paris SME

SME cybersecurity is no longer the business of paranoid specialists. It has become a first-rank operational risk, on par with cash flow or labour compliance. Two reasons: attacks have industrialised (ransomware-as-a-service, AI-generated phishing, vulnerabilities exploited within hours), and regulation is tightening with NIS2. Here are the priorities an IT services provider imposes on an SME in 2026 — ordered by priority and return on effort.

NIS2: why it concerns SMEs too

The NIS2 directive, being transposed into French law, massively widens the scope of entities subject to cybersecurity obligations. Many owners think they’re out of scope — wrongly:

  • The scope covers many sectors (energy, health, transport, digital, food, waste management, etc.), including medium-sized companies.
  • Even outside direct scope, SMEs that subcontract to or supply large accounts are now contractually held to security requirements. The subcontracting chain has become an audit vector.
  • Obligations include risk management, incident notification, and increased accountability for directors.

The message: don’t wait to be formally “in scope” before getting up to standard. The fundamentals below are expected, contractually or by regulation, ever more widely.

Priority 1: MFA everywhere, and passkeys

Single-password authentication is dead. MFA (multi-factor authentication) must cover all access: email, VPN, cloud apps, administration. And in 2026 we go further: phishing-resistant passkeys progressively replace SMS codes (interceptable) and even app codes. It’s the best security-to-cost move that exists.

Priority 2: EDR on every endpoint, Macs included

Classic antivirus no longer suffices against modern threats. EDR (Endpoint Detection & Response) monitors behaviour, detects anomalies and lets you isolate a compromised endpoint remotely. A crucial point too often forgotten: Macs are not immune. Attacks targeting macOS are rising, and an Apple fleet needs EDR built for macOS, not a recompiled Windows product.

Priority 3: tested backups (3-2-1)

Against ransomware, backup is the last line — provided it truly exists and you’ve tested it. The 3-2-1 rule: three copies of the data, on two different media, one of them off-site and offline (immutable). A permanently connected backup gets encrypted by the ransomware along with everything else. And a backup never actually restored isn’t a backup: it’s a hypothesis. We test restores, period.

Priority 4: zero-trust over the old VPN

The “castle wall” model (one VPN, and once inside you have everything) no longer holds against mobile and cloud usage. The zero-trust approach — systematically verifying identity, device and context at every access — has become the standard. For Mac teams, that means well-designed Conditional Access and, more broadly, a shift from VPN to ZTNA.

Priority 5: the human factor and AI-powered phishing

The unsettling novelty of 2025-2026: AI-generated phishing emails have become flawless — no typos, perfect tone, deep personalisation, even voice deepfakes for CEO fraud. Technique alone no longer suffices: you need regular awareness (simulated phishing campaigns, short repeated training) and verification procedures for sensitive actions (transfers, bank-detail changes). No filter stops 100% of messages; the team is the last rampart.

Priority 6: an incident response plan

The question isn’t if but when. A simple but written response plan — who to alert, how to isolate, how to communicate, in what order to restore — saves the decisive hours on the day. Without a plan, you improvise in panic, and that’s when you make the damage worse.

Our approach

We treat cybersecurity as a managed foundation, not an option: MFA and passkeys, multi-OS EDR, tested immutable backups, zero-trust, continuous awareness, monitoring and a response plan. All of it driven and measured, integrated into managed services, not sold piecemeal.

The good news: 80% of the risk is covered with well-laid fundamentals, without a large-group budget. If you want to know where you stand, an audit is the starting point — let’s talk through the contact form.
