Littlefish Group delivers managed cyber security services from CREST-accredited, UK-based security operations centres. Our CISSP-qualified analysts monitor, investigate and contain threats across your entire IT estate, 24/7/365.
24/7 threat detection and incident response from our CREST-accredited, UK-based SOC. Available in fully managed and co-managed models, covering Microsoft Sentinel SIEM, Gartner Magic Quadrant-recognised XDR technology, TTP-based threat hunting and our Critical Hour Framework for structured incident containment.
Zero trust architecture, cloud security posture management, identity controls and Microsoft Purview data loss prevention applied across your cloud environments, SaaS platforms and hybrid workforce.

Business continuity planning, disaster recovery, backup services and vulnerability management structured to reduce exposure across people, process and technology. Network scanning delivers impact-prioritised findings with remediation playbooks, so your organisation can identify, prioritise and close vulnerabilities before they become incidents.
Detection and response built for AI-enabled attacks: spear phishing, deepfakes and automated vulnerability exploitation. Combines adaptive machine learning with experienced analyst investigation to surface the anomalies, context shifts and behavioural patterns that signature-based detection is most likely to miss.
NCSC Cyber Assessment Framework assessments, CIS Microsoft 365 benchmark reviews, Cyber Essentials and Cyber Essentials Plus certification support, security architecture reviews, virtual CISO engagements and live-incident remediation playbooks for organisations that need demonstrated assurance alongside operational security.
Our analysts, our governance and your data all stay in the UK. We do not offshore our SOC and there are no international shift handovers.
In 2025 our UK-based SOC managed 175,000 incidents and neutralised more than 1,500 confirmed true positives across our client base.
We hold CREST SOC accreditation, ISO 27001, Cyber Essentials Plus and Microsoft Solutions Partner for Security, each audited and renewed annually.
Both scores are independently verified and have been sustained year on year across our managed services client base.
Operationally, Littlefish Group have been an excellent partner. From a collaboration perspective, we share the same goals. There’s never a time when they’re not contactable. Littlefish Group collaboratively work with our other providers, they’re always happy to take on other responsibilities, enhancing user experience via first time fixes and shift left responsibilities; their activities have been second to none.
Through a highly integrated approach, Littlefish Group has brought together the core service pillars that underpin NHS Supply Chain’s digital operations. These include Service Integration and Management, Modern Workplace solutions, a 24/7 Service Desk, and a dedicated Service Management Office. Together, these services enable us to deliver meaningful improvements that boost operational efficiency, enhance end-user experience, and ensure consistent, high-quality service delivery.
“Littlefish Group provide a dependable and professional out‑of‑hours and weekend service desk service, which is critical to maintaining continuity of our NHS services. Their team understands the demands of a 24/7 healthcare environment and responds promptly and effectively to support clinical and operational staff when it matters most. The service they deliver is reliable, well‑managed, and aligned with the high standards required to support patient care and frontline services.”
“Since the rollout of the solution, Muiríosa continues to transform what once was a static repository of information into a dynamic tool for communication and learning. Key documents, data and systems are now consolidated across Muiriosa’s 200 locations, ensuring information is accessible to everyone and maintaining transparency across the organisation.”
We are now a couple of months into our independent operation, and we’ve already begun to see a big difference; the speed of our support tickets has improved. We’re able to leverage and use a lot more of the Microsoft ecosystem.
“This is why we partnered with Littlefish, a managed IT and cyber services provider that is nimble and understands that our diverse structure means diverse solutions. We look forward to building this partnership over the coming months and years.”
“Since Littlefish have been appointed, they have been consistently delivering really excellent service to our staff. We have really tough expectations and have a sliding scale approach to customer satisfaction, so as the years go on, it gets harder. I’m really pleased to report that Littlefish have consistently met this scale.”
“It made sense to us to go to an organisation that could offer us a range of security services… we chose Littlefish because they could provide everything we needed. In an ever-evolving landscape, there’s always more to learn and new threats emerging, so I’m confident that Littlefish can help us with that.”
“We don’t see Littlefish as an ‘at arm’s length’ organisation, but as a partnership that works closely with us and that’s really important. We’ve really had great engagement in how they wish to understand our unique business and the way we operate and we’re starting to really reap the rewards of that engagement now.”
“Throughout the tender process it really did become obvious that Littlefish put customer service at the heart of their approach and were willing to get to know the Canal & River Trust as an organisation. Since go live the positive feedback has been overwhelmingly unanimous from across the organisation which reinforces the belief we have chosen the right partner.”
“We trust Littlefish to work closely with us and move processes along and remove the need for constant firefighting when it comes to mitigating cyber security risks. Littlefish helped us put our priorities in place and reach a level of security I’m 100% happy with.”
“Information security was becoming a bigger and bigger concern for the company, with pharmaceuticals being a highly regulated industry. For us, data security is paramount and cannot be underestimated – we needed a partner we could trust, one that could come in and hit the ground running and that was Littlefish.”
Compromised credentials and misused access tokens are now the primary entry point in the majority of breaches, not unpatched software or email-delivered malware. If your organisation cannot detect credential misuse before privilege escalation occurs, your exposure is significant regardless of the perimeter controls you have in place.
Every SaaS platform, cloud workload and API your organisation connects to its core infrastructure extends the attack surface. Without cloud security posture management and zero trust controls, misconfigured resources and implicit trust relationships create openings that are difficult to identify from within your own environment.
Attackers are using AI to generate more convincing phishing content, automate vulnerability scanning and produce deepfakes that bypass traditional identity verification. The organisations most exposed rely on signature-based detection rather than behavioural analysis and analyst-led investigation to identify anomalies and context shifts.
