High-Consequence Engagements — some are discussed. Some are not.
A subset of SIRI's work — litigation-sensitive investigations, executive crises, regulatory exposure, hostile or activist situations — is handled under engagement terms that limit what can ever be described publicly. That work is scoped individually, briefed to a narrow team, and closed out under the same discipline it was opened with. This page describes how that work is structured, not any specific client matter.
Core positioning
Discretion is a structural commitment, not a marketing phrase.
The engagements in this category are handled differently by design — narrower access, tighter documentation, and terms that limit public description.
High-consequence engagements typically involve one or more of: litigation-sensitive investigations, an executive-level crisis, regulatory exposure, or a hostile or activist situation directed at the client. These matters are scoped individually rather than run against a standard service description, briefed to a narrow, need-to-know team inside SIRI, and closed out under the same confidentiality discipline they were opened with.
Nothing on this page — or anywhere else on this site — describes an actual client matter. Where an engagement intersects with litigation or regulatory exposure, SIRI's investigative and forensic work can be coordinated with SIRI Law LLP's legal team; whether attorney-client privilege attaches depends on how and under whom the engagement is structured, and is assessed case by case — it is not automatic and is never assumed.
A related, standing capability under this practice is organisational resilience: crisis management planning, business continuity advisory, critical infrastructure advisory, and organisational resilience assessment — the preparation work that determines how well an organisation absorbs and recovers from a high-consequence event before one ever happens.
How high-consequence engagements are structured
Two components: the sensitive engagement itself, and the resilience work that precedes it
Every high-consequence engagement is scoped individually — these are the building blocks, not a fixed package.
Litigation-Sensitive Investigation Support
Investigative and forensic work scoped and structured for matters with active or anticipated litigation.
- Narrow, need-to-know team briefing
- Coordinated directly with SIRI Law LLP where privilege is relevant
- Documentation practices built for legal scrutiny
Executive Crisis Response
Coordinated response across intelligence, protective security, and legal counsel for an executive-level crisis.
- Rapid, coordinated cross-practice response
- Protective and reputational dimensions handled together
- Discreet engagement terms limiting public description
Crisis Management Planning
Pre-built decision frameworks for security and reputational crises, prepared before a crisis occurs.
- Documented decision frameworks and escalation paths
- Roles and responsibilities agreed in advance
- Tested through structured planning exercises
Business Continuity & Critical Infrastructure Advisory
Continuity planning for security-driven disruption, and risk and resilience advisory for critical facilities and systems.
- Business continuity planning for security-driven disruption
- Critical infrastructure risk and resilience advisory
- Organisational resilience assessment
Methodological alignment
Frameworks & standards our methodology draws on
Resilience and crisis planning under this practice draw on recognised business-continuity and risk-management standards.
Framework references reflect publicly available standards our methodology is aligned to; they are not a claim of certification, licensure, or law-enforcement authority. SIRI Security conducts all intelligence and investigative work through lawful, ethical means and does not misrepresent its personnel as government, law-enforcement, or intelligence-agency officials.
Why organisations bring high-consequence matters to SIRI
Narrow access, coordinated disciplines, and honesty about what privilege actually requires
The value in this category is structural discretion — not a promise SIRI is not positioned to make.
Narrow, need-to-know briefing
High-consequence matters are briefed to a small, defined team inside SIRI — not run through the same broad staffing model as routine engagements.
Legal coordination without false assurance
SIRI Law LLP can be engaged alongside investigative work, but SIRI is direct about the fact that privilege depends on engagement structure and is never automatic.
Cross-practice coordination in one firm
Intelligence, protective security, forensics, and legal coordination sit inside one organisation for these matters, reducing the number of parties with access to sensitive facts.
Resilience work before the crisis, not just during it
Crisis management planning and business continuity advisory reduce how much of a high-consequence response has to be improvised in the moment.

At closeFrequently asked
High-Consequence Engagements, answered directly
Can SIRI guarantee attorney-client privilege for these matters?
No. Whether privilege attaches depends on how and under whom an engagement is structured, and is assessed case by case with counsel — it is not automatic, and SIRI does not represent it as such.
Does this page describe an actual past client engagement?
No. Nothing on this page describes any specific client matter — it describes how SIRI structures this category of engagement.
What makes an engagement 'high-consequence' rather than a standard investigation?
Typically the presence of active or anticipated litigation, executive-level crisis exposure, regulatory risk, or a hostile/activist situation directed at the client — factors that call for narrower access and individually scoped terms.
Is the resilience planning work only relevant during an active crisis?
No — crisis management planning, business continuity advisory, and critical infrastructure advisory are typically most valuable before a crisis, reducing how much has to be improvised if one occurs.
Some conversations start confidentially
If a matter needs discretion from the first conversation, say so — the engagement is structured accordingly.
Start with a confidential scoping conversation. Terms and access are agreed before any work begins.
