What We Do
Professionalism. Accountability.
Integrity.
We are engaged where organisations, professional advisors and clients require intelligence collection, specialist investigative evidential support and independent assessment in complex, high-risk and sensitive environments.
SIS supports clients managing investigations, security and liability matters requiring structured evidential investigative strategies, continuity, and chain of custody assurance. We assist corporate functions including compliance, internal audit, organisational risk and HR, where internal matters require highly experienced independent investigative support.
In addition, through specialist protective intelligence capabilities, we support risk and security leaders manage emerging threats and hostile activity, including cases involving targeted harassment, hostile surveillance or directed activity towards individuals, assets and organisations. We provide actionable intelligence and evidential operational support to inform proportionate risk mitigation, supporting legal proceedings / remedies and decision making in dynamic, high risk contexts.
Intelligence
SIS delivers structured intelligence collection and analysis to identify vulnerabilities, establish context and reduce uncertainty before resources are committed.
Our intelligence collection operations provide comprehensive understanding of vulnerabilities across processes, environments, networks, people, behaviours and emerging threats.
This intelligence informs investigative strategies, directs proportionate evidence collection and supports defensible, highly informed decision making.
The result is improved efficiency, reduced investigation costs, stronger governance and earlier identification of organisational / personal risk.
Investigations & Evidence.
Organisations are rarely exposed to risk because an investigation was unwarranted.
Risks often arise when investigative strategies or processes lack governance.
SIS delivers intelligence-led investigations that connect information, intelligence, evidence and risk within a structured, defensible framework providing evidential continuity, chain of custody, provenance and reporting standards embedded to ensure our findings withstand legal challenge, regulatory scrutiny and executive oversight.
We support complex, sensitive and high consequence investigations including blackmail, insider threat, organised criminality, child safeguarding concerns, multi-jurisdictional matters, fraud and workplace / corruption investigations.
Regardless of complexity our objective is simple: establish fact, reduce uncertainty, mitigate risk and support confident, highly informed, defensible decision making.
Protective Intelligence.
SIS assists organisations identify, assess, evidence and mitigate threats before escalation to crisis response.
Through lawful targeted intelligence collection, analysis and assessment relating to environments, operations, assets and people, SIS supports informed, proportionate decision-making in high consequence environments that strengthen resilience and reduce risk.
Our capabilities, delivered to evidential standards, include protective surveillance, counter surveillance, behavioural analysis, technical surveillance, technical surveillance counter measures, counter intelligence and specialist operational support to Crisis Management Teams.
Proactively we enable organisations to identify, evidence and anticipate threats, protect people and assets, and implement proportionate measures before risk becomes consequence.
Reactively, we integrate intelligence and evidence collection together with specialist operational capabilities supporting CMTs and existing security functions through the deployment of highly experienced personnel supporting some of the UK's highest consequence investigations including K&R, abduction, adverse targeting and stalking.
Intelligence. Evidence. Risk
SIS helps organisations make confident, defensible decisions by integrating intelligence, evidence and risk within a single integrated investigative strategy.
In protective intelligence environments we identify, evidence and manage emerging threats before they become crises.
From complex and sensitive corporate investigations to adverse targeting, executive risk, hostile reconnaissance and specialist operational support to crisis teams, we integrate intelligence, evidence and structured risk management to reduce uncertainty and support informed, proportionate and defensible decisions.

Trust,
Discretion,
Assurance.
Specialist Investigative Support is engaged where intelligence, investigation, evidence gathering and risk management directly influence outcomes in complex, sensitive and high-consequence environments.
Every investigation is ultimately about supporting a decision.
Whether addressing litigation, employee misconduct, executive risk, corporate governance or organisational resilience, confidence comes not from the volume of information obtained, but from the quality of the intelligence, the integrity of the evidence and the ability to understand and manage risk.
Continuity across complex matters.
SIS integrates intelligence, evidential discipline and structured risk management into a single decision-support framework.
By clearly defining intelligence requirements before investigative activity begins, we ensure resources remain focused, proportionate and aligned to agreed objectives. This reduces uncertainty, avoids unnecessary investigative activity, manages financial and operational risk, and delivers measurable outcomes within agreed budgets .
The result is more than a completed investigation. It is a decision that can be explained, justified and defended. By integrating intelligence, evidence and risk throughout every engagement, SIS provides organisations with greater certainty, stronger governance and the confidence to make informed, proportionate and defensible decisions capable of withstanding scrutiny.
