The Threat Reality

Why cyber security
cannot wait.

43% of cyber attacks now target small and mid-sized businesses. The average cost of a UK data breach is £3.4 million. And 60% of SMEs that suffer a significant cyberattack go out of business within six months. The question is not whether your business will be targeted — it's when.

Threat

Ransomware & Malware

Ransomware attacks have increased 400% since 2021. A single infected endpoint can encrypt your entire network within minutes. Our EDR platform detects behavioural anomalies and isolates threats before encryption begins.

Threat

Business Email Compromise

The UK's most financially damaging cyber crime. Attackers spoof trusted senders to redirect payments or steal credentials. Our advanced email filtering, DMARC enforcement, and staff training dramatically reduce exposure.

Threat

Supply Chain Attacks

Attackers increasingly target trusted software vendors and IT suppliers to gain access to their customers. We assess your supply chain risk profile and implement controls that limit the blast radius of third-party compromises.

Threat

Insider Threats & Data Leakage

Whether accidental or malicious, insider threats account for 22% of incidents. Data Loss Prevention (DLP) policies, privileged access management, and user behaviour analytics detect and prevent unauthorised data movement.

Our Security Services

Defence in
depth.

No single security control is sufficient. We deploy multiple, overlapping layers of protection — ensuring that if one control fails, others continue to protect your business.

24/7 Security Operations Centre monitoring of all logs, alerts, and events across your estate. Threat correlation, anomaly detection, and direct incident response by our security analysts.

The CITS Difference

Security expertise
you can trust.

Cyber security is not software you buy — it's expertise you retain. Our security team combines technical depth with business acumen to deliver protection that's both effective and practical.

CREST Certified

Our penetration testers hold CREST certifications, the gold standard for assurance testing. All testing follows CREST methodology and produces fully documented reports.

24/7 SOC Coverage

Threats don't work 9-to-5. Our Security Operations Centre monitors your environment around the clock, with real security analysts — not just automation — reviewing alerts.

Integrated with IT Management

Because we also manage your IT, security findings translate directly into patching, configuration changes, and hardening — no gap between finding and fixing.

Insurer-Approved Controls

Our security controls and documentation are designed to satisfy cyber insurance requirements, helping you qualify for coverage and potentially reduce premiums.
