Close the gaps attackers use most

What are the biggest cyber risks for UK small businesses?

Phishing is the most common route in. The UK Government's Cyber Security Breaches Survey 2025 found 43% of businesses identified a breach or attack in the previous 12 months, and phishing was by far the most common type. Account takeover, invoice fraud and ransomware usually follow from a single stolen password.

• Phishing emails that steal Microsoft 365 or Google passwords.
• Invoice and payment fraud from hijacked email accounts.
• Ransomware through unpatched devices or exposed remote access.
• Data loss from no backups, or backups the attacker can also reach.

What is Cyber Essentials and do you need it?

Cyber Essentials is a UK Government-backed scheme, run through IASME, that certifies five basic controls: firewalls, secure configuration, user access control, malware protection and security update management. It is required for many UK public sector contracts and increasingly requested by larger customers. It also proves to insurers and clients that the basics are covered.

Devsinn prepares you for Cyber Essentials and Cyber Essentials Plus by putting the required controls in place and documenting them. Certification is assessed and awarded by an accredited certification body, not by us.

How much does cyber security cost for a small business?

A Cyber Essentials readiness review starts from £1,250 + VAT. Microsoft 365 security hardening starts from £1,500 + VAT, and ongoing monitoring, patching and backup management from £150 + VAT a month for small teams. We quote fixed prices after a short review of your current setup.

What does Microsoft 365 hardening involve?

Hardening means changing default settings to safer ones. We enforce multi-factor authentication, block legacy sign-in methods, set conditional access rules, protect admin accounts, turn on audit logging, tighten external sharing, configure email protection against spoofing with SPF, DKIM and DMARC, and set alerts for suspicious sign-ins.

How do you protect backups from ransomware?

Backups must be separate from the systems they protect, so attackers cannot delete them. We use immutable or offline copies, keep a retention history, back up Microsoft 365 or Google data as well as files and servers, and test restores regularly. You get a written recovery plan with realistic timings.
