Sector cybersecurity

Security for legal, accountancy and professional services.

Professional firms depend on client trust, confidentiality and reliable access to matter, finance and collaboration systems.

Discuss your requirements

Common exposure

Threats and operating realities.

The right controls depend on the organisation’s services, information, suppliers and existing technology. These are common areas to explore, not an assumption that every organisation has the same risk.

  • •Targeted invoice and supplier payment fraud
  • •Phishing and mailbox compromise
  • •Confidential client data shared too broadly
  • •Insurer and tender security questionnaires

Practical security focus

Build around important services and data.

Strengthen mail, identity and endpoint controls
Review access to client files and collaboration spaces
Make payment-change verification clear
Prepare proportionate evidence for client and insurer reviews

Services to consider

Email security

Email remains a route to people, credentials and payments. A layered approach combines technical filtering and reporting with sensible identity controls and staff awareness, designed around your mail platform and working practices.

Identity and access security

Identity determines who can reach systems and data. Strong identity controls combine authentication, least-privilege permissions, careful administration and regular review of accounts as people and responsibilities change.

Security awareness and phishing readiness

People need clear, practical guidance on recognising and reporting suspicious activity. Awareness works best when it supports technical controls and gives staff a simple, blame-free way to raise concerns.

Cybersecurity assessments

An assessment gives decision-makers a structured view of current controls, relevant exposure and practical priorities. AOS engagements start with a free 30-minute review; any deeper technical assessment is scoped separately before it begins.

Frequently asked questions

Can your recommendations support an insurer questionnaire?

A clear control review and remediation plan may help inform responses. The organisation remains responsible for accurate answers and must not claim controls that are not implemented.

Do small firms need managed security?

It depends on exposure, internal capability and risk appetite. An initial review helps identify proportionate next steps rather than assuming one package fits all.
