Cybersecurity That Protects What Matters Most
Layered defences, constant vigilance, and the expertise to keep your business secure without slowing it down.
The Threat Landscape Has Changed
Every month, we block an average of 2,847 threats across our client base. Most of them arrive by email. The rest come through compromised websites, stolen credentials circulating on the dark web, and vulnerabilities in unpatched software.
In 2026, cyber attacks against UK businesses are up 38% year on year. Ransomware gangs specifically target professional services and financial firms because they hold valuable data and face pressure to pay quickly. The question is not whether your business will be targeted, but whether your defences will hold when it happens.
What Real Cybersecurity Looks Like
Effective cyber security for business is not a single product. It is a set of overlapping controls, each designed to catch what the others miss.
We start with endpoint detection and response on every device. Unlike traditional antivirus, EDR watches for suspicious behaviour patterns — a script executing in memory, a process trying to disable security tools, or an application reaching out to a known command-and-control server.
Email security sits in front of your inboxes, analysing every message for phishing links, malicious attachments, and impersonation attempts. We tune these filters specifically for your organisation, whitelisting legitimate senders and flagging imposters.
DNS filtering prevents your team from reaching malicious websites, even if they click a link in a convincing phishing email. Dark web monitoring alerts us when your company credentials appear in breach databases, so we can force password resets before attackers use them.
Financial Services Expertise
We understand the regulatory pressures facing FCA-regulated firms. Our cybersecurity services in London are designed to satisfy the specific requirements of DORA, SYSC 13, and the FCA’s operational resilience framework. We maintain evidence packs that map each control to the relevant regulation, making audit season significantly less painful.
For hedge funds and PE firms, we also address the unique risks of deal-sensitive information, investor data, and high-value wire transfers that attract business email compromise attacks.
Straightforward, Not Scary
We do not use fear to sell security. We present the risks plainly, explain what controls address them, and let you make informed decisions about how much protection your business needs. Every recommendation comes with a clear rationale and a cost-benefit analysis.
Why choose Nerdster
Defence in Depth
No single product stops every attack. We layer multiple security controls so that if one fails, the next catches it. Redundancy is the point.
Compliance Without the Headache
We map our security stack directly to FCA, DORA, and Cyber Essentials frameworks so your audits are smoother and your evidence packs are always current.
Business-Aware Security
We configure security controls around how your people actually work, not how a textbook says they should. The result is strong protection with minimal friction.
FAQ
Frequently asked questions
Do we need cybersecurity services if we already have antivirus?
Traditional antivirus catches known threats. Modern attacks use fileless malware, living-off-the-land techniques, and social engineering that antivirus cannot detect. EDR, email filtering, and user training close those gaps.
How do you handle a security incident?
We follow a documented incident response process: contain, investigate, remediate, and report. For clients on our managed security plans, incident response is included at no extra charge.
Can you help us achieve Cyber Essentials certification?
Yes. We help clients prepare for and pass both Cyber Essentials and Cyber Essentials Plus. We handle the technical controls and guide you through the assessment process.
What about insider threats?
Our monitoring includes anomalous behaviour detection on endpoints and in Microsoft 365. If someone starts exfiltrating data or accessing systems outside their normal pattern, we flag it immediately.
How does this work with our existing IT setup?
Our security tools integrate with most environments. We deploy alongside your existing infrastructure, whether that is on-premise, cloud, or hybrid, and whether we manage your IT or another provider does.
