Real-time attack mapping, CVE intelligence, APT actor profiles, and IOC data aggregated and curated by the CT Cyber Defence SOC team. Refreshed continuously from global threat feeds.
Elevated ransomware activity. APT42 and Scattered Spider actively targeting UK/EU financial sector.
High-severity CVEs actively exploited in the wild, curated from NVD, CISA KEV, and our own threat hunting telemetry. Last updated May 2025.
Nation-state, cybercriminal, and hacktivist groups actively targeting organisations in our client sectors. Profiles based on current intelligence and MITRE ATT&CK mappings.
Highly sophisticated espionage group targeting government, diplomatic, and technology organisations. Known for long-dwell-time intrusions, supply chain attacks (SolarWinds), and Microsoft 365 credential theft via password spray and OAuth abuse.
Dual-mission group conducting both state-sponsored espionage and financially motivated cybercrime. Prolific use of zero-day exploits, supply chain compromises, and destructive tools alongside ransomware deployment for financial gain.
English-language cybercriminal group specialising in social engineering for MFA bypass and SIM-swapping. Responsible for high-profile breaches of MGM Resorts, Caesars, and multiple telecom providers. Deploying ALPHV/BlackCat ransomware.
Prolific ransomware-as-a-service group. Despite law enforcement takedown attempts in 2024, remains active with reconstituted infrastructure. Uses intermittent encryption for speed, exfiltrates data before encryption for double extortion.
Iranian state intelligence group conducting credential harvesting, surveillance, and destructive attacks against journalists, human rights organisations, government, and critical infrastructure. Active spear phishing campaigns targeting UK targets in 2025.
Pro-Russian hacktivist group conducting DDoS campaigns against NATO member state government, banking, and critical infrastructure. Uses Telegram to recruit DDoS participants and announce targets. Primarily availability-focused, limited intrusion capability.

Our SOC team monitors all of the above actors and IOCs 24/7 — and actively hunts for their TTPs across client environments. Find out if you're already exposed.
We begin with a no-obligation scoping call to understand your infrastructure, current tooling, and the threats most relevant to your sector and risk profile.
Log collectors, agents, and integrations are deployed across your environment. Our Elastic SIEM begins ingesting data and our analysts start baselining within 48 hours.
We tune detection rules to your environment, reducing noise and ensuring alerts are meaningful. Custom playbooks are built around your specific technology stack.
Your environment is now fully covered. Threats are detected, triaged, and responded to around the clock — with weekly executive reports keeping you fully informed.
We leverage best-in-class security tooling — integrated into a unified SOC platform that delivers visibility without complexity.
CT Cyber Defence is a specialist cybersecurity services provider delivering 24/7 Security Operations, threat detection, and incident response. We operate an advanced Elastic-based security platform offering continuous visibility across endpoints, networks, and cloud environments.
Our approach combines SIEM, EDR, and proactive threat hunting with experienced human analysts to minimise risk, strengthen resilience, and maintain operational continuity. We bring enterprise-grade capability to organisations that demand it — at a price point that makes sense.
Founded by Sandeep Mothukuri, a hands-on SOC engineer with deep expertise in the Elastic Stack, incident response, and adversary emulation. We don't just monitor — we actively defend.
Hands-on security operations experience, not theoretical consulting. We've run SOCs — we build ones that actually detect and respond.
Deployment and baselining in 48–72 hours. Rapid time-to-value with no lengthy integration cycles or expensive professional services engagements.
A credible alternative to large MSSP vendors — without sacrificing detection fidelity, response capability, or visibility coverage.
Security solutions aligned to your exact infrastructure, risk profile, and sector. Not a one-size-fits-all package with generic playbooks.
Our managed SOC generates audit-ready evidence for the most demanding regulatory frameworks — helping you stay secure and compliant simultaneously.
Information Security Management System standard. We map controls, identify gaps, and provide the continuous monitoring evidence auditors need for certification and annual surveillance.
Trust Services Criteria for SaaS and cloud companies. Our 24/7 monitoring directly satisfies Availability, Confidentiality, and Security criteria — with continuous log evidence for auditors.
Technical and organisational measures required under GDPR Article 32. Our SOC covers breach detection (Art. 33), data access anomaly monitoring, and supports DPA notification timelines.
Payment Card Industry standards for organisations handling cardholder data. We satisfy Requirements 10 (log monitoring), 11 (intrusion detection), and 12 (security policies) through our managed platform.
Security Rule compliance for healthcare organisations handling PHI. We implement the administrative, technical, and physical safeguard requirements — with continuous audit logging for covered entities.
UK government-backed certification scheme covering the five critical controls. Our team has guided multiple organisations through CE+ certification — and our SOC directly satisfies malware protection and monitoring requirements.
CT Cyber Defence provided immediate visibility into our entire security posture. Their SOC team detected a credential stuffing campaign we had completely missed. Response was fast and communication was exceptional throughout.
Their proactive threat hunting surfaced a dormant APT that had been inside our network for weeks. Highly professional, technically excellent, and unlike any MSSP we've worked with before. Genuinely different.
Affordable, highly capable, and genuinely enterprise-grade. As an SME we couldn't afford a big MSSP. CT Cyber Defence gave us the same quality of protection at a fraction of the cost. Outstanding value.
Anonymised case studies from live engagements — real threats detected, contained, and resolved by our SOC team.
Challenge: A UK fintech startup was under sustained credential stuffing targeting their customer portal — 40,000 automated login attempts over 3 hours, undetected by their existing WAF.
Challenge: A healthcare organisation onboarded with CT Cyber Defence for compliance monitoring. During baselining, proactive threat hunting surfaced a dormant implant that had been resident for 21 days.
Challenge: A 200-seat SaaS company faced a phishing-delivered loader that established persistence and began lateral movement. Encryption had not yet started when SOC analysts intervened.
