Cybersecurity leadership for decisions that cannot stay fragmented.
Antares helps mid-market leadership teams clarify risk, assign decision ownership, and govern the security program over time.
In plain English: a Virtual CISO (vCISO) is a senior security leader who works with your executive team on a defined cadence, without requiring a full-time hire.
A 30–45 minute advisory conversation. If there is a fit, Antares proposes scope.
- No dedicated security leadership
- A CISO transition, growth, or restructuring
- Board, audit, or enterprise customer pressure
- Security ownership fragmented across teams and providers
- Compliance or program work with no clear owner
vCISO Engagement — Specialty Services Company
Following the departure of its internal CISO, a specialty commercial services company with a 32-vendor delivery network needed security governance rebuilt around clear decisions. An Antares principal led the vCISO advisory engagement, working alongside the client's internal audit and finance functions.
- 32 third-party vendors brought under active, ongoing risk management
- 22-document policy and procedure library formalized
- Governance committee and defined cadence operating within 37 days
The initial 90-day engagement transitioned into an ongoing vCISO retainer at the client's request, continuing the governance cadence, vendor risk oversight, and compliance roadmap support.
Assess. Design. Govern.
A three-phase model for understanding risk, building the right program, and governing it over time.
Assess
Establish a defensible view of risk. Where the organization stands, where exposure actually sits, and which gaps deserve leadership attention.
Design
Translate findings into the program: structure, controls, sequencing, and the operating model that fits the business, not a generic framework.
Govern
Run the program with leadership. Keep priorities current, oversee execution, and produce the cadence boards expect, without theater.
Security outcomes are produced by clear decisions made at the right level, under real constraints, and sustained over time.
Most security programs don't fail for lack of tools or effort. They fail when it's unclear who is responsible for the decision.
Three core services.
Each covers a distinct part of the work and can be engaged on its own or in sequence.

The Antares Decision Model.
A framework for making better cybersecurity decisions. Understand, decide, execute, improve — in a loop that keeps the program honest as conditions change.
What clients should expect from the engagement.
Four operating principles that shape how the practice is delivered at the level of the engagement itself, not the marketing around it.
Senior-Level Engagement
Every engagement is led directly by a senior principal. The person in the scoping conversation is the person doing the work, accountable to the executive team and visible to the board.
Decision-Oriented Advisory
Work is structured around the decisions leadership will actually face. Output is shaped for executive review and risk acceptance, not assessment binders that sit unread.
Operationally Grounded
Strategy is delivered alongside the operating model that runs it. Control architecture, vendor governance, and reporting cadence are defined to be operated, not described.
Long-Term Governance Focus
Engagements are sized for the program's real horizon: audit cycles, board cadence, and the multi-year arc of a maturing security function, not isolated projects.
Supporting work scoped alongside core engagements.
Threat Management
Vulnerability and exposure management aligned to business priority: what to fix, in what order, and how to stop the queue from running the program.
Penetration Testing
Scoped, targeted testing focused on systems and risks that matter, with findings written for executives and engineering, and a clear remediation path.
Infrastructure & Cloud Security
Architectural review and hardening across cloud and hybrid environments: identity, segmentation, data flow, and the controls that meaningfully reduce blast radius.
Start with the decision the program needs to support.
Most engagements begin with a 30–45 minute advisory call covering operating context, current risk posture, and the decisions that are forcing the work. If a fit exists, we propose a scoped diagnostic or retainer tied to specific outcomes.

- Compliance readiness engagements
- Operational security leadership
