Cyber Essentials for Professional Services Firms | Accountants, Brokers & Consultants
The professional services industry operates on a foundation of intimate client relationships and absolute trust. Unlike other sectors, professional service providers, whether solicitors, accountants, architects, graphic designers, web developers, or consultants, are entrusted with their clients' most sensitive and valuable information.
Show clients, insurers and partners that you take data, trust and security seriously.
Professional services firms run on trust. Clients send sensitive information, sign documents, share financial details, rely on advice, and expect their data to be handled properly.
Cyber Essentials gives your firm a recognised way to show that the basic security controls are in place. It helps reduce common cyber risk, supports client assurance, and gives you something clear to point to when tenders, insurers or partners ask about security.
This page is for accountants, consultants, recruitment agencies, insurance brokers, mortgage brokers, wealth managers, financial advisers and other data-driven professional businesses that want security to feel practical rather than painful.

“Can we trust you with our data?”
Most clients will not phrase it like that. They may ask for a supplier questionnaire, an insurance requirement, a tender document, a due diligence check or proof of cyber controls.
Cyber Essentials gives your firm a simple, recognised way to answer that question with more than “we take security seriously”.
It turns good intentions into visible assurance.
Client confidence
Professional firms handle contracts, financial records, payroll data, CVs, reports and confidential information. Certification helps show clients that security is being taken seriously.
Cyber insurance support
Cyber Essentials can support insurance conversations by showing that recognised technical controls have been reviewed and improved.
Competitive advantage
If another firm cannot show the basics are in place and you can, that can matter during tenders, onboarding and supplier reviews.
Reduced common risk
The controls push your firm towards better access control, safer devices, secure configuration, malware protection and timely updates.
Clearer gaps
Many firms are not sure what is protected, what is outdated, or what could block certification. The process gives you a clearer view.
A practical first step
Cyber Essentials is not the whole cyber security story. It is a strong place to start and a useful foundation for wider assurance.
Five core controls that make your firm harder to attack.
Firewalls and internet gateways
Helps make sure devices and systems are not unnecessarily exposed to the internet.
Secure configuration
Reduces risk from default settings, unnecessary accounts, weak permissions and avoidable exposure.
Access control
Helps make sure the right people have access to the right systems, accounts and data.
Malware protection
Supports protection against malware, ransomware and malicious activity on business devices.
Security updates
Helps reduce exposure to known vulnerabilities by keeping systems and software up to date.
What that means for you
Better basics across the laptops, cloud accounts, software and systems your team uses every day.

Useful for firms where email, documents, cloud accounts and client trust sit at the centre of the business.
What are the essential cyber security practices for insurance brokers?
Insurance brokers often access client data through online portals, email, cloud systems and insurer platforms. That makes account security, strong passwords, multi-factor authentication, secure devices, patching and staff awareness especially important.
Cyber Essentials helps brokers prove that key technical controls are in place, including access control, secure configuration, malware protection, firewalls and security updates.
It will not cover every risk, but it gives brokers a recognised baseline to support client trust, supplier checks and insurance conversations.

Cyber Essentials
A recognised certification focused on five core technical controls. Ideal when clients, insurers or suppliers want evidence that the basics are in place.
Broader assuranceSMB1001
A broader cyber assurance route for micro and small businesses. Useful when you want a wider plan across people, process, technology and ongoing improvement.
Cyber Essentials is a strong start. Professional firms often need wider protection too.
Certification helps with the basics. Real-world risk often sits around email fraud, Microsoft 365 account compromise, staff decisions, backup and recovery.
Protect against phishing and fake payment emails
Reduce malicious links, spoofing, file scams and fake payment requests reaching your team.
IdentitySpot Microsoft 365 account takeover
Watch for unusual logins, malicious inbox rules and signs someone else is inside an account.
Staff awarenessHelp staff spot scams earlier
Practical training around phishing, fake documents, payment redirection and suspicious links.
BackupRecover Microsoft 365 data
Protect mailboxes, OneDrive, SharePoint and Teams data if something is deleted, encrypted or compromised.

View cyber security for professional servicesQuestions professional services firms ask about Cyber Essentials.
Is Cyber Essentials worth it for a small professional services firm?
Yes. Smaller firms still handle sensitive client data, contracts, financial information, employee records, candidate data and trusted email conversations. Cyber Essentials helps show that recognised basic controls are in place.
Will Cyber Essentials stop all cyber attacks?
No. It is a strong baseline, not a guarantee. Many firms also need stronger email security, identity monitoring, backups, endpoint protection and staff awareness.
Can Cyber Essentials help with tenders and client due diligence?
Yes. It can give your firm a recognised security certificate to include in supplier checks, tenders, client onboarding and due diligence requests.
Can Cyber Essentials help with cyber insurance?
It can help support cyber insurance conversations because it shows that key controls have been reviewed. Insurers may still ask about MFA, backups, endpoint protection, patching and incident response.
What is the difference between Cyber Essentials and SMB1001?
Cyber Essentials focuses on five core technical controls. SMB1001 is broader and can help smaller businesses build a more complete cyber assurance plan across people, process and technology.
Can you help us prepare before we apply?
Yes. We can review your current setup, identify likely problem areas, help fix gaps and guide you through the submission process.
What cyber security controls should insurance brokers have when accessing client data online?
Insurance brokers should use strong passwords, multi-factor authentication, secure business devices, timely software updates, malware protection, controlled access to client systems and clear processes for spotting phishing or fake payment requests. Cyber Essentials helps check several of these core controls.
Is Cyber Essentials relevant for accountants, brokers and consultants?
Yes. Professional services firms often handle client records, financial information, contracts, payroll data, CVs and confidential documents. Cyber Essentials gives these firms a recognised way to show that basic security controls have been reviewed.
What is the best cyber security standard for a small professional services firm?
