Hybrid working security challenges in 2026 — what’s changed for UK SMEs
Hybrid working is stable now: staff split time between home, client sites and the office, and it isn’t going away. That matters because the security assumptions that worked for a single office no longer apply. For owners and managers of UK businesses with 10–200 staff, the real question isn’t whether hybrid is risky — it’s which risks to fix first, who pays for each fix, and when to call for help.
Which security gaps should you prioritise?
Start with the things that let attackers get in and move fast: identity, device hygiene and backups. Identity problems — weak sign‑ons, unmanaged accounts and inconsistent multi‑factor authentication (MFA) — are the most immediate threat to hybrid teams. The single fastest fix we make in our first month with a new client is closing MFA gaps — most new tenants are 24 hours of work away from hardened, and almost no one is doing it.
After identity, look at device patching and endpoint protections. Laptops and phones used on home networks can carry unpatched vulnerabilities that let attackers leap from a single compromised device into corporate systems. Backups are your insurance: hybrid means a wider attack surface for ransomware, so you need reliable, tested restores rather than a hope that files will come back.
Practical prioritisation for an SME usually follows a simple rule: fix the things attackers use first (identity and MFA), then reduce blast radius (patching, principle of least privilege), then harden recovery (backups, segmentation). For day-to-day guidance that fits hybrid staff, see our remote working guidance which frames those choices around staff behaviour and business continuity.
Who should own hybrid security in your business?
There are three common models: a named internal owner (operations, IT or a senior manager), a small internal team with external support, or a managed service provider (MSP). For businesses with fewer than about 50 staff, a single responsible manager plus strong external technical support usually gives the best balance of cost and coverage. For larger SMEs, pairing an internal lead with an MSP for 24/7 tooling and monitoring works well.
Ownership is not just about who presses the buttons. It’s about accountability: who signs off on MFA roll‑outs, who approves conditional access rules, who pays for device replacement, and who enforces acceptable use. Give someone a short, explicit remit (for example: ensure 100% MFA coverage, monthly patching cadence, tested backups every quarter) and a handful of measurable targets.
The National Cyber Security Centre provides useful resources for boards and small business leaders that can help frame those responsibilities; their general advice can be a concise checklist when you’re allocating roles and budget. For an introduction see NCSC’s guidance on cyber security topics.
How much should you budget?
Budget conversations are always political. The right framing is risk reduction per pound spent. Some high‑impact actions cost almost nothing: enforcing MFA, removing legacy accounts, and rolling out a clear password manager policy have modest fees but large returns. Others — device replacement, advanced endpoint detection, or network segmentation — are real investments and should be justified by the risk they reduce.
Think of expenditure in tiers: immediate fixes (hourly or small uplift), foundational investments (annual licences, device refresh cycles), then resilience and detection (ongoing monitoring and incident response). For many SMEs the lion’s share of risk is removed in the first tier; after that you can make measured choices about detection and resilience depending on how sensitive your data is and how damaging an outage would be.
When should you bring in outside help?
Bring in outside help when the internal owner lacks time, specialist skills, or authority to make changes quickly. If incidents have already occurred, or you need continuous monitoring, an MSP with a clear service level agreement can be more cost‑effective than hiring full‑time specialists.
Outside help is also sensible when you need to demonstrate controls to customers or insurers: an external attestation that MFA is enforced, backups are tested, and a remote access policy is in place carries weight in commercial discussions. If you choose an MSP, pick one that explains trade‑offs clearly and sets measurable deliverables rather than selling an opaque bundle of tools and alerts.
How will you measure success?
Good measures are tangible and limited. Useful KPIs for hybrid security include MFA coverage across active accounts, time‑to‑patch for critical vulnerabilities, percentage of devices with up‑to‑date endpoint protection, phishing test click rates, and the recovery time from a simulated restore. Track those quarterly and let them guide where budget and attention go next.
Remember that numbers matter to the board: reducing high‑risk accounts by 80% is a clearer story than “improving security”. Use simple metrics you can report in a one‑page update.
Practical next move for a small business owner
Pick one person to own the first 30 days, and make the immediate goal concrete: audit all active accounts, confirm MFA on every admin and staff account, and verify backups for critical data are restorable. Those actions take time but are high impact — and they’re the same steps we prioritise when we help leaders get control.
If you want a quick win this week, run an MFA coverage check and close any gaps you find. That action reduces immediate exposure, frees management time otherwise spent firefighting, and strengthens your commercial credibility with customers and insurers.
Contact a trusted adviser or MSP and ask for a short, 30‑day security plan focused on identity, device hygiene and backup recoverability. The right first month delivers measurable reductions in risk, a clearer budget picture, and more calm in your senior team.
