Cyber security solutions — protection, detection and response for small businesses
Cyber security solutions are the combination of software, policies and services that prevent, detect and contain breaches; common elements include endpoint protection, Microsoft 365 configuration, firewalls and an incident response plan. Small UK firms should treat them as an operational kit, not a one-off purchase.
How quickly can you detect and respond?
Speed matters: the faster you detect an intrusion, the lower the financial and reputational damage. Practical solutions combine continuous monitoring (SIEM or simpler EDR alerts), a clear escalation path and a tested incident playbook. Look for vendors or services that commit to a measurable detection SLA — for example, detection within 24 hours and initial containment actions within 4 hours are reasonable targets for an SME with limited internal IT.
Operational signals to check:
- Where are alerts sent? (Email alone is weak — prefer paging or an on-call rota.)
- Who owns incident triage internally? (Outsource if you have no security lead.)
- Can the provider run forensics and contain an infection remotely?
If you plan to buy monitoring, ask for a recent incident playbook and a reference showing a live response: the difference between an alerted system and an acted-on alert is decisive.
Can it stop business email compromise?
Business email compromise (BEC) is the sort of attack that can erode trust and cash quickly. From our experience, the single most common cyber incident we handle for UK SMBs is business email compromise — a stolen Microsoft 365 password, no MFA, a spoofed invoice sent from the real mailbox. The whole attack runs in under an hour from credential theft to fraudulent invoice. That combination of speed and legitimacy makes BEC hard to spot unless your stack is configured correctly.
Controls that materially reduce BEC risk:
- Multi-factor authentication (MFA) on Microsoft 365 and all financial logins.
- Blocking legacy authentication and enforcing modern protocols in Office 365.
- Outbound email alerts for unusual activity and verification checks on high-value payments.
When evaluating solutions, ask for concrete proof: can the supplier show log examples of blocked BEC attempts, and do they offer configuration hardening for Microsoft 365 as part of the package?
Does it meet compliance and audit needs?
Buying security partly for compliance is normal. Decide whether you need a baseline (Cyber Essentials), evidence for contracts, or full-certification (ISO 27001). Technical controls such as patching, MFA and least privilege cover many tender requirements; formal certification fills the gap where procurement teams demand paperwork.
Check whether the solution provides:
- Documentation you can present at audit (policies, change logs, access reviews).
- Regular vulnerability scans or penetration-testing reports.
- Support for data-protection obligations under the ICO (data breach notification workflows).
If you want a single reference for government-backed baseline controls, consider reviewing NCSC’s guidance on cyber security and map any supplier’s controls back to it before you sign.
Operational fit and cost predictability
Security must fit the way your business works. A high-end managed SOC is overkill for many firms with 10–200 staff; what matters more is clear responsibilities, predictable monthly pricing and a plan for staff training. Evaluate total cost of ownership: software licences, onboarding, configuration, and the recurring cost of monitoring or managed response.
Ask suppliers these operational questions before choosing:
- Who will configure Microsoft 365 and test MFA enforcement?
- What are ongoing charges for incident response and forensic work?
- Can the provider integrate with your existing IT support or accounting systems?
You can compare options quickly by scoring each supplier on four criteria — detection speed, BEC controls, audit evidence and operational fit — then weighting those scores by what matters most to you. If you want a ready place to start, review the detail on our cyber security services page to see how those elements are combined into an ongoing package.
Putting the criteria together when comparing options
When you review proposals, use a simple matrix: list detection SLA, MFA and email-hardening steps, evidence for audits, and a clear monthly price. Score each supplier from 1–5 on those headings and multiply by your weighting (for many firms detection and BEC controls should weigh highest). Prefer suppliers that include configuration work up front and a short SLA for containment.
As a practical next step, ask any shortlisted provider to show a recent, redacted example of an incident they detected and contained — that will reveal whether they really act on alerts or just produce dashboards. A short procurement checklist reduces guesswork and keeps budget predictable while improving resilience.

FAQ
How quickly can business email compromise steal money?
From our experience, a typical BEC attack can move from credential theft to a fraudulent invoice in under an hour, which is why fast detection and MFA are essential.
Is Cyber Essentials enough to win public sector tenders?
Cyber Essentials is often accepted as a minimum for low-risk tenders, but medium or high-risk contracts usually require additional evidence such as ISO 27001 or specific supplier questionnaires; check the contract notice for exact requirements.
How much should I budget for managed detection and response?
For a business of 10–200 staff, expect managed detection and response to start around GBP 600–£1,500 per month depending on scope and whether endpoint licences are included.
Can I protect my business without hiring a security specialist?
Yes — many firms combine a managed service with an internal IT lead; ensure the supplier provides configuration hardening, MFA rollout support and an incident playbook so your existing team can act quickly.
