Cyber Essentials in City of London
Government-backed cyber security certification for businesses in the Square Mile, from gap assessment through to submission — delivered by a team based right here in the City of London.
Five Core Controls
We assess and, where needed, remediate against all five Cyber Essentials technical controls — firewalls, secure configuration, patching, access control and malware protection.
Certification & Plus
We support you through the self-assessment questionnaire, and through the external technical audit if you're going for Cyber Essentials Plus.
Ongoing Compliance
Certification is renewed annually — we offer ongoing IT support so your controls stay in place between renewals, not just on assessment day.
Cyber Essentials certification for City of London businesses
Cyber Essentials is a UK Government-backed certification scheme, supported by the National Cyber Security Centre, that verifies five baseline technical controls are in place across your organisation: firewalls, secure configuration, security update management, user access control and malware protection. For financial services, insurance, banking, fintech, legal and accounting firms in the City of London, it's increasingly the starting point for client due diligence, insurer questionnaires and public-sector tenders. We help businesses across the Square Mile assess where they stand, close the gaps that are found, and get certified — with the technical remediation work carried out by the same team, not handed off to someone else. As with the rest of our work, everything is priced with a fixed quote after a free consultation, and delivered remotely with on-site visits around the City of London where needed.
Cyber Essentials in City of London
The City of London — the Square Mile — is the historic financial heart of the UK, home to the Bank of England, Lloyd's of London and the London Stock Exchange. It's the densest concentration of financial and legal firms in Europe, with over 500,000 people working here daily across banking, insurance and professional services. That concentration of regulated, client-facing business is exactly why Cyber Essentials comes up so often in Square Mile conversations — as a condition of a tender, an insurer's renewal questionnaire, or a client's own supplier due diligence.
Why Cyber Essentials Matters in the Square Mile
Financial services, insurance, banking, fintech, legal practices and accounting firms all handle client data and money in ways that invite scrutiny. A Cyber Essentials certificate gives clients, insurers and regulators a recognised, government-backed signal that your basic technical controls are in place, without requiring you to build a security programme from scratch.
Working With City of London Businesses
We're based here ourselves, at New London House, EC3R — close to the Bank of England and the Lloyd's Building — so we know the pace and the compliance pressure that come with operating in the Square Mile. Most of the certification work is done remotely, with on-site visits arranged locally when hardware genuinely needs hands.
Our approach to Cyber Essentials certification in City of London
A Straightforward Gap Assessment First
We start by reviewing your current setup against the five Cyber Essentials controls — firewalls, secure configuration, security update management, user access control and malware protection — and give you a clear, prioritised list of what needs to change before anything else happens.
Hands-On Support Through to Certification
Where remediation is needed, we do the technical work ourselves rather than just handing you a report, then support you through submission and, if you're going for Cyber Essentials Plus, the external technical audit.
How it works
From first conversation to certificate in hand — our process keeps things simple and clearly explained at every stage.
1
Discovery
We learn about your systems, devices and how your team works, so we understand your starting point before anything else.
2
Gap Assessment
We review your setup against the five Cyber Essentials controls and give you a clear, prioritised list of what needs to change.
3
Remediation
We close the gaps we've found — configuration, patching, access control and malware protection — remotely, with on-site visits around the City of London where needed.
4
Certification & Renewal
We support you through submission and, for Plus, the technical audit, then keep your controls maintained ahead of annual renewal.
City of London businesses turn to us when
Their business is asked for Cyber Essentials as a condition of a new client contract or tender
Their cyber insurance renewal now requires evidence of baseline security controls
Their firewall and device configurations have never been formally reviewed against a recognised standard
Staff use a mix of personal and company devices without a clear access control policy
Patching and software updates happen inconsistently across the team
They've grown quickly and their original ad hoc IT setup hasn't kept pace
A larger corporate client or regulator has asked what security certifications they hold
They want Cyber Essentials Plus but haven't yet achieved base-level certification
Their existing IT provider doesn't offer compliance or certification support
Why choose Cloudswitched for Cyber Essentials in City of London?
We're an IT services and digital agency based in the City of London, which means Cyber Essentials isn't a bolt-on service for us — it sits alongside the day-to-day IT support, web and infrastructure work we already do for businesses in the Square Mile.
We assess your systems against the five Cyber Essentials controls in plain English, without assuming you already know the jargon, and give you a realistic view of what needs to change and why.
Where remediation work is needed — firewall configuration, secure device builds, patching, access control — we carry it out ourselves, so you're not left holding a gap-assessment report with nowhere to take it.
For firms that already have an IT provider, we can run the Cyber Essentials project alongside your existing setup rather than asking you to switch everything to us.
After certification, we offer ongoing IT support so the controls that got you certified stay maintained, ready for annual renewal rather than slipping in between.
Why Cloudswitched for Cyber Essentials?
We don't just hand you a checklist — we help you actually meet it. Here's what sets us apart.
On your doorstep in the City of London
Our team works from New London House, EC3R, right in the City of London, so on-site visits are quick to arrange when remote work alone isn't enough.
Plain-English gap assessments
We translate the Cyber Essentials requirements into a clear, practical list of what your organisation needs to change, rather than a wall of jargon.
We handle the technical remediation too
Many providers stop at advice. We can also carry out the firewall, configuration, patching and access control work the assessment requires, so the same team takes you from gap to certificate.
Works alongside your existing IT provider
If you already have IT support in place, we can run the Cyber Essentials project alongside them rather than asking you to switch everything over.
Understands financial and legal sector pressure
Based among banks, insurers, fintechs and law firms in the Square Mile, we see first-hand the due diligence questions clients, regulators and insurers ask of businesses here.
Fixed quote, no surprises
After a free consultation we give you a fixed quote for the certification project, so there's no open-ended billing while you wait for a result.
Remote-first, on-site when it counts
Most of the assessment and remediation work can be done remotely; we book on-site visits around the City of London for the parts that genuinely need hands on hardware.
Support that continues after the certificate
We stay involved after certification with ongoing IT support, so the controls that got you certified don't quietly slip before renewal.
Technology Infrastructure for Cyber Essentials in City of London
Businesses across the City of London depend on properly configured firewalls, access controls and patching processes to meet the Cyber Essentials standard and keep client and regulator confidence intact. In a Square Mile dominated by financial services, insurance, banking, fintech and legal practices, a well-managed technical baseline isn't just a certification exercise — it's part of day-to-day risk management. Managed IT support helps firms in the area keep those controls in place between certification cycles, rather than scrambling to fix gaps at renewal time.
About the City of London
The City of London — universally known as the Square Mile — is one of the world's oldest financial centres, built up over the centuries around the Bank of England and the insurance market that grew into Lloyd's of London. Today it hosts the London Stock Exchange alongside banking, insurance, fintech, legal and accounting firms, drawing several hundred thousand people into its offices on a typical working day.
Business landscape: The mix of financial services, insurance, banking, fintech, legal practices and accounting firms operating within the Square Mile means client confidentiality, regulatory scrutiny and insurer due diligence are a constant background pressure — all of which Cyber Essentials speaks to directly.
Getting here: We're based in the City of London ourselves, at New London House, EC3R, so on-site visits for Cyber Essentials remediation work involve no travel time at all — Square Mile firms can usually have someone from our team on-site the same day if hardware genuinely needs attention.

Frequently Asked Questions
Got questions? We've answered the most common ones below. If you need more detail, get in touch.
What is Cyber Essentials and do I need it?
Cyber Essentials is a UK Government-backed certification scheme, supported by the National Cyber Security Centre, that verifies your organisation has five baseline technical controls in place: firewalls, secure configuration, security update management, user access control and malware protection. It isn't legally mandatory for every business, but it's increasingly asked for as a condition of government contracts, insurance renewals and client due diligence, particularly across financial services, legal and insurance firms in the City of London.
What's the difference between Cyber Essentials and Cyber Essentials Plus?
Cyber Essentials is a self-assessment questionnaire, reviewed and verified by an external assessor. Cyber Essentials Plus adds a hands-on technical audit of your systems, giving a higher level of assurance. Many City of London firms working with regulated clients or public-sector contracts opt for Plus once they've achieved base-level certification.
How much does Cyber Essentials certification cost?
We provide a fixed quote after a free consultation, based on the size of your organisation and the state of your existing IT environment. There's no one-size-fits-all price, because every firm's starting point is different.
How long does the process take?
It depends on how close your current setup already is to the five required controls. Some City of London firms with well-managed IT are ready to submit within a few weeks; others need a period of remediation first. We'll give you a realistic view of your own timeline after the initial assessment.
We already have an IT provider — can you still help?
Yes. We're often brought in specifically for Cyber Essentials because it needs a structured gap assessment and documentation that day-to-day IT support doesn't always cover. We work alongside your existing provider or handle everything ourselves, whichever suits you.
Do you work with financial services and legal firms specifically?
We're based in the City of London ourselves, at New London House, EC3R, in the middle of the Square Mile's financial and legal services community. We understand the compliance pressures firms here are under from regulators, insurers and larger corporate clients.
Will Cyber Essentials cover everything our insurer or clients ask for?
Cyber Essentials establishes a solid technical baseline, but some insurers, regulators or corporate clients ask for additional assurance beyond it. We'll talk you through where Cyber Essentials fits within your wider compliance picture during the free consultation.
Do you offer ongoing support after certification?
Cyber Essentials certification is renewed annually, and your IT environment will keep changing in between. We offer ongoing IT support plans so the controls you've put in place stay maintained rather than slipping before your next renewal.
