CISOs can obtain insurance aimed at liabilities arising from their work, including a product AIG names “CISO Side A Liability Insurance.” But that does not mean every CISO is automatically covered, or that one policy covers every kind of claim. Depending on the role, protection may involve Side A or other directors and officers (D&O) insurance, cyber insurance, and professional liability or errors and omissions (E&O) insurance. Availability and coverage depend on jurisdiction, underwriting, and the wording of the policy.
What CISO professional liability insurance means
“Professional liability” is often used as an umbrella term for insurance against claims alleging mistakes or negligence in professional services. It does not identify one standard policy that covers every CISO exposure. A corporate CISO facing a claim over executive decisions may need different protection from an independent consultant accused of providing deficient security services.
AIG publishes a product called CISO Side A Liability Insurance, designed for alleged acts by corporate data officers and data departments acting in management and professional capacities. That is evidence that a CISO-specific product exists, not a guarantee that it is offered in every country or that a particular person, claim, or employer qualifies. AIG notes that products may not be available in all jurisdictions and that actual policy language controls.
How Side A, D&O, cyber, and E&O differ
These policy types address overlapping but distinct risks. Travelers describes D&O as covering defense costs, awards, and settlements arising from actual or alleged wrongful acts by directors or officers. Its CyberRisk description addresses expenses associated with cyber events or breaches, including forensic investigation, legal, and regulatory-defense costs. Professional liability or E&O generally concerns alleged errors, omissions, or negligence in professional services.

#1 Best Overall
| Coverage type | Typical focus | Why a CISO might ask about it |
|---|---|---|
| Side A D&O | Protection for insured directors and officers when the organization cannot indemnify them, subject to the policy terms. | Ask whether the CISO is an insured person and whether the policy responds when the company cannot or does not indemnify. |
| Entity-inclusive D&O | Claims against covered directors, officers, and, where the form provides, the organization. | May be relevant to claims alleging wrongful management acts; the CISO’s status and the claim’s allegations matter. |
| Cyber insurance | Costs tied to a cyber incident or breach, potentially including forensic, legal, and regulatory-defense expenses, as described by Travelers. | May address incident-response costs, but should not be assumed to provide personal protection for every claim against an individual CISO. |
| Professional liability / E&O | Alleged errors, omissions, or negligence in professional services. ARC describes its miscellaneous professional liability as covering errors and omissions in services provided to others for a fee. | Especially relevant when a CISO or consultant provides paid security advice or services and a client alleges those services were deficient. |
Side A is a part of the D&O coverage conversation, not a synonym for cyber or E&O. Aon’s July 25, 2024 webinar on CISO liability specifically addressed how D&O and cyber policies may work together and their potential coverage limitations. The practical point is to assess the policies as a coordinated set rather than assume that a cyber policy automatically protects an individual executive.
What employed CISOs should check with their employer
Start with the actual policy documents or a written coverage summary, not the policy name alone. Ask the company’s risk manager, legal team, or broker to confirm the answers in writing.
- Insured-person definition: Does it expressly include the CISO, and does coverage apply to the role and capacity in which the person acts?
- Side A protection: Is there Side A coverage if the organization cannot indemnify the CISO? What conditions and exclusions apply?
- Defense arrangements: Are defense costs advanced as claims proceed, and what rules govern selection or approval of counsel?
- Claims-made terms: What is the policy’s retroactive or prior-acts date, and what notice and reporting deadlines apply? A missed reporting deadline can matter even when the alleged conduct occurred during the relevant period.
- Claim types: How does the wording treat regulatory investigations, shareholder claims, cyber incidents, and claims by the organization or another insured?
- Limits and retention: What limits, sublimits, and deductibles or retentions apply, and are defense costs inside or outside the limit?
- Exclusions and severability: Which exclusions could affect the CISO, and can another insured person’s conduct or knowledge affect that person’s coverage?
- Territory: Where must the conduct, claimant, or proceeding be located for the coverage to apply?
What independent CISOs and vCISOs should consider
An independent virtual CISO (vCISO) or security consultant may provide advice or services to clients for a fee. In addition to asking about any D&O or cyber protection available through a client or employing organization, the consultant should evaluate professional liability or technology E&O designed for those services. The relevant question is whether the policy covers the actual work performed—not simply whether the person’s title includes “CISO.”
Markel says its E&O serves consultants and service organizations, while CFC lists professional liability and technology E&O products. Zurich also describes professional-liability coverage for professional and technology-service exposures. These category descriptions do not establish that a particular vCISO program is available, or that a policy covers a given contract, service, or allegation. A broker should review the services offered, client agreements, and policy definitions together.

How to evaluate a quote before relying on it
- Describe the work and role precisely. Tell the broker whether the applicant is an employee, officer, independent consultant, or service firm, and list the security, advisory, and management services actually provided.
- Identify the intended insureds and capacities. Confirm by name or policy definition who is covered and whether the policy applies to the relevant corporate or consulting role.
- Map the policy layers. Determine whether the proposal is Side A, entity-inclusive D&O, cyber, professional liability/E&O, or a coordinated combination. Ask what claims each policy is intended to address.
- Review defense and claims-made mechanics. Confirm advancement of defense costs, counsel arrangements, prior-acts treatment, notice rules, and any extended reporting option.
- Read the exclusions and claim definitions. Ask specifically about regulatory matters, shareholder claims, insured-versus-insured wording, cyber-related allegations, and severability.
- Compare limits, retentions, and territory. Establish how limits apply across claims and policies, whether defense costs erode limits, and where coverage applies.
- Verify jurisdiction and final wording. Ask a licensed broker to confirm availability and explain differences between the quote, binder, and issued policy. The issued policy’s terms govern.
Are premiums or recommended limits publicly established?
No generally applicable CISO premium, recommended limit, or claim-frequency statistic is established by the cited sources. Pricing and limits depend on underwriting and the applicant’s circumstances; a jurisdiction-specific broker quote is needed rather than a generic figure.
