IT Services & Cybersecurity for UK Professional Services

Why do professional services firms need managed IT?

Professional services firms hold confidential client records, process financial transactions and usually run lean without in-house IT. That combination makes them an attractive fraud target and a hard place to recover after an incident. Managed IT support closes the gap with continuous monitoring, certified engineers and tested backups.

According to the UK government's Cyber Security Breaches Survey 2025, 43% of UK businesses experienced a cybersecurity breach or attack in the previous 12 months. Firms that bill against filing deadlines feel downtime hardest — an outage during a tax or audit deadline is lost revenue and a client-trust problem at once.

Common attack vectors against professional services firms:

• Business email compromise (BEC) — fraudulent invoice redirection and payment-instruction scams that exploit trusted client relationships
• Phishing — credential theft targeting Microsoft 365 and practice-management logins
• Ransomware — timed to deadlines, when firms are most likely to pay to keep working
• Insider error — misdirected client data, a reportable breach under UK GDPR

What's included in AMVIA's managed IT for professional services?

AMVIA delivers a single, accountable stack: email security, Microsoft 365 management, endpoint protection, helpdesk and backup. Each layer is configured by Microsoft-certified engineers and monitored by our in-house team, so a firm with no internal IT department still gets enterprise-grade controls. AMVIA serves firms with 10-500 staff.

• Email security and anti-BEC — Barracuda email filtering with DMARC, DKIM and SPF enforced, plus impersonation protection to block payment-redirection fraud
• Microsoft 365 management — security configuration, conditional access, data-protection policies and licensing handled end to end
• Device and endpoint security — Microsoft Defender for Endpoint on every laptop and mobile, covering office and remote staff
• Unlimited UK helpdesk — phone, email and chat support that resolves day-to-day issues fast
• Backup and business continuity — immutable backups of client files, mailboxes and practice-management data with tested recovery

Microsoft Defender for Endpoint is Microsoft's endpoint detection and response (EDR) tool; AMVIA configures and monitors it 24/7 in-house rather than handing alerts to a third party.

In-house IT vs managed IT for professional services firms — which is right?

Most firms under 500 staff cannot justify a full in-house security team, yet still face the same threats as larger practices. Managed IT delivers the coverage of a department for a predictable per-user fee. The table below compares the two models on the factors that matter to a managing partner.

How does managed IT protect against business email compromise?

BEC attacks impersonate a client, partner or supplier by email to redirect a payment or extract financial details — and AI-generated messages have made the impersonation harder to spot. AMVIA blocks it with layered email authentication and access controls rather than relying on staff to catch every fake.

The National Cyber Security Centre recommends DMARC, DKIM and SPF to stop attackers spoofing your domain. AMVIA configures all three, enforces multi-factor authentication on Microsoft 365, and adds impersonation filtering so spoofed director and client emails are quarantined before they reach a fee earner. Payment-change requests are routed through a verification step, not a reply-to address.

What UK GDPR obligations do professional services firms have for client data?

Professional services firms are data controllers under UK GDPR and must apply appropriate technical and organisational security measures to the client data they hold. That means access control, encryption, documented breach procedures and the ability to act fast when something goes wrong.

Under ICO rules, a notifiable personal data breach must be reported to the regulator within 72 hours. AMVIA's managed IT supports UK GDPR compliance with MFA, encryption, immutable backups and audit logging — the controls an ICO investigation expects to see evidenced.

Professional services IT and security checklist

Use this as a baseline. AMVIA implements and monitors every item as part of managed IT, so nothing is left to chance between busy periods.

• MFA enforced on all cloud services — Microsoft 365, accounting software, practice-management systems and client portals
• Email security controls active — DMARC, DKIM and SPF configured with anti-phishing filters
• Client data backed up and tested, with offsite immutable copies
• UK GDPR measures in place — privacy notice, data-processing register, retention policy and DPIA process
• Staff security-awareness training covering phishing, BEC, password hygiene and data handling
• Remote access secured with MFA through approved channels only

How much does managed IT for professional services cost?

AMVIA's managed IT for professional services starts from £30/user/month, covering helpdesk, security tooling, Microsoft 365 management and backup under one fee. Pricing scales with headcount and the licences a firm needs.

Microsoft licensing sits alongside the service. Microsoft 365 Business Premium — which includes Defender for Business and Intune — lists at £16.90 per user per month (ex VAT, annual) on microsoft.com. AMVIA manages those licences so you pay list price without the admin overhead. For a firm of 25 staff, that is one predictable number against the salary, tooling and cover cost of an in-house hire.
