The sector today
Growth puts new demands on your IT
The systems that suit a team of twenty rarely suit a firm of two hundred. Security questionnaires, hybrid working and AI have raised the bar for everyone.
Professional services firms, technology companies and other knowledge-based businesses have a few things in common. Their product is expertise, their people work from anywhere, and their most valuable asset is information that belongs to clients. That makes them attractive targets: technology and professional firms report more cyber breaches and attacks than any other part of the economy. It also means larger clients, insurers and regulators increasingly ask for evidence of good security before they will sign a contract, typically Cyber Essentials, ISO 27001 or a detailed security questionnaire.
Many organisations reach this point with IT that grew by accident: several file-sharing tools, unmanaged laptops and phones, shared passwords, and nobody quite sure who has access to what. Staff, meanwhile, have started using AI assistants on their own initiative, sometimes pasting client material into public tools. Anthrasec helps corporate organisations bring this under control. We standardise the workplace on a secure platform, move the right workloads to the cloud, put managed security and monitoring in place, prepare you for certification, and roll out AI in a way that improves productivity without leaking data.

of UK businesses review the cyber security risks posed by their immediate suppliers, and only 6% look at their wider supply chain
92%
less likely to make a cyber insurance claim: organisations certified to Cyber Essentials, compared with those without it

of large businesses have a formal cyber incident response plan, compared with 21% of micro businesses
Knowledge-based firms are attacked most often
Technology and professional services businesses are the most likely to identify a cyber breach or attack. They hold valuable client data and rely heavily on email and cloud services, which is where most attacks begin.

The pressures
Six risks business leaders ask us about
Each one is manageable with the right controls. Here is what's at stake, and how we respond.
Client security due diligence
- The risk
- Tenders and renewals stall on security questionnaires, Cyber Essentials or ISO 27001 requirements.
- Our response
- We prepare the controls, policies and evidence, and help you answer questionnaires accurately.
Email fraud and phishing
- The risk
- Criminals impersonate executives and suppliers to trick staff into paying false invoices or sharing passwords.
- Our response
- Email authentication, filtering, multi-factor authentication and payment verification procedures.
Hybrid working on unmanaged devices
- The risk
- Company data ends up on personal laptops and phones that you can't secure or wipe.
- Our response
- Managed devices, conditional access and data protection that follows the file.
Unapproved AI tools
- The risk
- Staff paste confidential material into public AI tools, with no record or control.
- Our response
- An approved set of AI tools, a clear usage policy and controls that keep data inside your own environment.
Outgrown systems
- The risk
- Overlapping tools, ageing servers and improvised processes slow people down and hide risk.
- Our response
- One consolidated platform, cloud migration where it pays, and retirement of what's no longer needed.
Joiners, movers and leavers
- The risk
- Accounts and access linger after people change role or leave.
- Our response
- Automated provisioning, regular access reviews and single sign-on across your applications.

AI at work
Productive AI, without the data leaks
Your people are probably using AI already. The priority is to give them approved tools that are safe with client information, and the skills to use them well.
60%
of leaders worry that their organisation lacks a plan and vision for implementing AI, according to a survey of 31,000 people in 31 countries
Drafting and summarising
Copilots that draft documents, summarise meetings and help people catch up on long threads.
Safeguard: Permissions are tidied first, so the assistant only surfaces what each person is allowed to see.
Knowledge search
Assistants that answer questions from your own policies, precedents and project files.
Safeguard: Answers cite the documents they came from, and data stays within your own environment.
Proposals and reporting
First drafts of bids, board packs and client reports, built from your templates and data.
Safeguard: A named person reviews and owns everything sent to a client.
Finance and back-office automation
Invoice capture, expense checks and reconciliations handled automatically.
Safeguard: Approval limits and exception queues keep people in control of payments.
When it matters most
A convincing phishing email: how a prepared firm stops the fraud
Business email compromise is one of the most common and costly attacks on professional firms. This is how layered controls and our monitoring service are designed to stop it.
Illustrative scenario showing how our service is designed to work. Response times are agreed with each client and set out in their service agreement.
09:12
Phish
A finance manager receives a realistic 'shared document' email and enters their password on a fake sign-in page.
09:13
Block
The attacker tries to sign in from abroad. Conditional access and multi-factor authentication refuse the attempt.
09:20
Detect
Our analysts see the risky sign-in alert, confirm the password was stolen and reset the account.
09:35
Check
Mailbox rules, recent sign-ins and other recipients of the same email are reviewed. Nothing else is affected.
Same day
Verify
A request to change a supplier's bank details arrives. Your call-back procedure catches it before any payment is made.
Afterwards
Learn
Staff get a short briefing based on the real example, and the fake domain is blocked for everyone.

Common questions
Corporate IT and security, answered
Can you act as our IT department, or work with our existing IT team?
Either. You can hand us day-to-day IT and security entirely, or keep your in-house IT manager or provider and use us for security monitoring, cloud and projects. We agree clear responsibilities at the start.
How long does it take to get ready for Cyber Essentials?
It depends on your starting point. Organisations with well-managed devices and accounts can be ready within a few weeks. Others need longer to replace unsupported software or bring devices under management. We assess the gaps first and give you a realistic timescale. Certification itself is awarded by a certification body.
Are we ready for Microsoft 365 Copilot?
Copilot can surface anything a person already has access to, so readiness is mostly about your data. We review permissions and sharing, tidy up overshared sites, apply sensitivity labels and train staff, then roll out to a pilot group before going wider.
Can you help us answer client security questionnaires?
Yes. We help you answer accurately, point to the evidence behind each answer and close the gaps that questionnaires reveal, so the next one is quicker.
We already have an IT provider. Why add Anthrasec?
General IT support keeps systems running. Specialist security monitoring, certification readiness, cloud engineering and AI governance need different skills. We work alongside your provider and fill those gaps.
What size of organisation do you work with?
Our services suit organisations from small professional firms to those with several hundred staff and multiple offices. The services are the same; we scale them to your size, risks and budget.
