Why professional services firms are in the crosshairs

It is worth being direct about who is at risk. Recruitment agencies handle candidate personal data, employment histories, salary information, and in some cases medical records. Accountancy practices hold client financial records, payroll data, tax returns, and bank account details. HR consultancies and business consultants routinely manage commercially sensitive material that clients would never want in the public domain.

That combination of high-value data and typically lean internal IT resource makes these firms an attractive target regardless of size. A 2026 survey by insurer Everywhen found that 65% of professional firms now rank cyber-attacks as their single biggest business concern, well ahead of economic pressures, regulatory change, and professional negligence claims. That is not a marginal shift. It reflects a lived reality.

For a recruitment firm mid-campaign or an accountancy practice in the middle of a client audit, the operational disruption from a ransomware attack can be severe. The reputational damage lasts considerably longer. And for firms handling personal data under GDPR, a breach carries regulatory consequences with real financial weight.

IT support and cybersecurity are not the same thing

Many firms believe they are covered because they have antivirus software, a firewall, and an IT support contract. Those things matter. But they do not add up to a managed cybersecurity service.

IT support covers maintenance, helpdesk access, and reactive problem-solving. It keeps systems running. Managed cyber security services do something different: they actively protect those systems, monitor them for unusual behaviour, and ensure there is a plan in place when something goes wrong.

The distinction matters because attackers do not announce themselves. They use automated tools to scan thousands of systems simultaneously, looking for weaknesses. When they find one, they move quickly and quietly. Without active monitoring, that activity goes undetected until the damage is already done.

What managed cybersecurity actually covers

A properly structured managed cybersecurity service includes several interconnected layers. Each one addresses a different part of the risk picture.

1. Endpoints
   Covers every device your team uses, not only machines in the office. With hybrid working standard across professional services, a laptop connecting from a home network is as much of an entry point as anything on-premise.
2. Email
   Filters phishing attempts and blocks business email compromise, still the starting point for the overwhelming majority of attacks on UK businesses.
3. Monitoring
   Ensures that when unusual activity is detected, it is detected quickly. Speed of detection makes a material difference to how much damage an attacker can do before they are stopped.
4. Response
   A tested, defined process for containment and recovery when something happens. A policy document that has never been rehearsed is not an incident response plan.
5. Compliance
   Helps firms achieve and maintain Cyber Essentials, Cyber Essentials Plus, and ISO 27001. The NCSC advises SMEs to look for these certifications when choosing a managed service provider, because they act as genuine quality and trust indicators.

Microsoft 365 security needs active management

For most professional services firms, Microsoft 365 is now the operational backbone. Email, documents, collaboration, and identity all sit in one place. Default configurations alone are not enough. A managed cybersecurity service should include active management of your M365 environment: multi-factor authentication, conditional access, email threat protection, and monitoring for compromised accounts. The platform holds too much to leave on default settings.

The skills problem sitting behind all of this

Growth in managed cybersecurity services is not only driven by rising threats, though threats have risen. It reflects a straightforward skills reality: most small and mid-sized firms in professional services do not have the internal expertise to manage cybersecurity complexity alongside everything else involved in running a business.

Industry research consistently finds that two thirds of UK SMEs plan to increase their reliance on managed security services, with the primary driver being a lack of specialist in-house skills (37%), followed closely by the need to meet compliance and regulatory requirements (36%).

Outsourcing to a provider whose job it is to stay current with an evolving threat landscape is a sound operational decision. For most firms in recruitment and professional services, it also delivers better protection at a lower cost than attempting to build equivalent capability in-house.

The compliance picture right now

Regulatory pressure on professional services firms is increasing. GDPR requires breach notification to the ICO within 72 hours. Fines can reach 4% of annual global turnover, and recent enforcement has demonstrated that regulators are willing to use those powers. The UK government’s Cyber Security and Resilience Bill will expand obligations further, with stronger reporting requirements across a wider range of sectors.

For firms working with larger enterprise clients, cyber certification requirements are increasingly written into contracts. Cyber Essentials is the UK government’s baseline standard. It is not especially complex to achieve, but it does require disciplined, maintained controls rather than a one-time exercise. A good managed cybersecurity provider should guide you through certification and keep those controls current over time.

The human element

Technology controls address only part of the risk. People remain the most reliable entry point for attackers and the most underestimated one.

Phishing is still the most common attack vector, with criminals increasingly using sophisticated social engineering to impersonate clients, HMRC, suppliers, and internal colleagues. For a busy team at a recruitment firm or accountancy practice, an urgent email about a payment or a shared document is not always easy to identify as malicious.

The firms that manage cyber risk most effectively are those where good security habits are part of day-to-day working, not reserved for a once-a-year reminder. Cybersecurity awareness training is not an optional extra. It is part of the service.
