A tested incident response plan, clear roles and tabletop exercises, coordinated with your IT team, insurer and response retainer.
Fractional CISO services provide an experienced Chief Information Security Officer on a part-time, contracted basis. The fractional CISO is accountable for the organization's cybersecurity program: security strategy, risk management, policies, compliance, incident readiness and reporting to leadership, without the cost of a full-time security executive.
Fractional CISO services are also known as virtual CISO or vCISO services. They are designed for organizations that face real cyber risk and compliance obligations, such as customer security questionnaires, SOC 2 or ISO 27001 audits, HIPAA or PCI DSS requirements, or cyber insurance conditions, but do not have a dedicated security executive to own them.
DESSS delivers cybersecurity consulting from Houston and Austin, Texas, across cloud security, identity and access management, Microsoft security, security operations, data protection and governance, risk and compliance. A DESSS Fractional CISO leads your program and can bring in these specialists when a specific control needs to be designed or implemented.
A fractional CISO owns an organization's cybersecurity program. They assess security risk, set the security strategy and roadmap, write and enforce security policies, guide compliance and audits, prepare incident response, oversee security tools and providers, and report cyber risk to executives and the board.
The areas below make up a complete cybersecurity program. Your fractional CISO prioritizes them according to your risk, obligations and budget.
A security strategy aligned to business priorities, risk appetite and obligations, defining what the security program must protect and how maturity will improve over time.
Framework-based assessments of people, processes and technology, combined with technical checks, to produce an evidence-based view of your security posture.
Roles, responsibilities, committees and reporting that make security a managed business function rather than an IT side task.
Identify, score and treat cyber risks in terms leadership understands, with documented decisions to mitigate, transfer, avoid or accept each risk.
A right-sized policy set, including information security, acceptable use, access control, data classification and incident response, mapped to your framework.
Guidance through SOC 2, ISO/IEC 27001, HIPAA, PCI DSS, CMMC and customer security requirements, from readiness to audit.
An incident response plan with roles, playbooks and communication steps, tested through tabletop exercises before a real incident happens.
Role-based training and phishing simulation that measurably change behavior, with extra focus on executives, finance and IT administrators.
A repeatable process to find, prioritize and fix vulnerabilities across endpoints, servers, cloud and applications, with agreed remediation timeframes.
Tier vendors by the access and data they hold, assess them proportionately, and include the right security terms in contracts.
Security architecture and guardrails for Microsoft Azure, AWS, Google Cloud and SaaS, including configuration baselines and posture monitoring.
Guide the identity program: multi-factor authentication, single sign-on, least privilege, privileged access and regular access reviews.
Review designs for new systems, networks and integrations, and guide the move toward zero trust principles.
A sequenced, budgeted plan of security initiatives, prioritized by risk reduction and compliance deadlines.
Bring all of the above together into an operating security program with owners, metrics, cadence and continuous improvement.
What organizations gain from a fractional CISO engagement with DESSS.
Gain CISO-level expertise for the time your organization needs instead of funding a full-time executive role.
Security spending is directed at the risks most likely to cause material harm, based on a documented assessment.
Documented controls and evidence make audits, customer security reviews and questionnaires quicker to complete.
A tested plan and clear roles reduce confusion and delay when an incident occurs.
Evidence of controls such as MFA, backups and incident planning supports cyber insurance applications and renewals.
Leadership receives regular, plain-language reporting on cyber risk and program progress.
A CISO is a full-time security executive employed by one organization. A fractional CISO carries the same accountability for the security program but works part-time under a service agreement. The fractional model gives smaller and mid-sized organizations executive security leadership in proportion to their size and risk.
| Factor | Full-time CISO | Fractional CISO |
|---|---|---|
| Employment model | Permanent executive employee | Contracted part-time executive |
| Cost structure | Salary, bonus, benefits, recruiting and retention | Monthly retainer or defined project fee |
| Availability | Dedicated full-time | Scheduled time plus agreed incident availability |
| Time to start | Often a long search in a competitive market | Typically weeks after scoping |
| Experience base | Deep knowledge of one organization | Experience across many environments and incidents |
| Scalability | Fixed | Increase for audits or incidents, reduce when stable |
| Best suited to | Large or highly regulated enterprises with continuous demand | SMBs, mid-market and growing regulated firms |
A fractional CISO is also different from a managed security service provider (MSSP) or SOC. An MSSP monitors and responds to alerts; a fractional CISO sets the strategy, owns the risk decisions and holds the MSSP accountable.
A company needs a fractional CISO when it has meaningful cyber risk or security obligations but no dedicated security executive to own them. The need usually becomes visible through a customer requirement, an audit, an insurance renewal or an incident.
Security obligations vary by sector. DESSS fractional CISOs tailor controls and compliance priorities to your industry.
HIPAA Security Rule risk analysis, medical device and third-party risk, and patient data protection.
GLBA and regulator expectations, fraud-related controls and strong vendor oversight.
IT and OT security coordination, remote site connectivity and critical infrastructure concerns.
Ransomware resilience, OT network segmentation and supply chain security requirements.
CMMC and NIST SP 800-171 readiness for handling Controlled Unclassified Information.
SOC 2, secure development practices and customer security reviews.
Client confidentiality, email security and data handling requirements from clients.
PCI DSS scope reduction, payment security and customer data protection.
The Fractional CISO engagement process moves from risk discovery to an operating security program. Timelines are typical and depend on your environment and obligations.
We confirm your business context, regulatory and contractual obligations, current providers and immediate concerns.
Framework-based assessment with interviews, document review and technical checks across identity, endpoints, cloud, network and data.
Risks and obligations are turned into a prioritized, budgeted security roadmap agreed with leadership.
Security roles, policies, procedures, vendor risk and incident response are put in place.
Your fractional CISO leads roadmap initiatives, oversees providers, supports audits and customer reviews, and handles escalations.
Security metrics and risk status are reported to leadership, and the roadmap is re-prioritized as threats and the business change.
DESSS pairs experienced security leadership with specialist cybersecurity teams, so every recommendation can be implemented and evidenced.

The fractional CISO coordinates with your CIO, IT team or DESSS Fractional CIO so security and IT roadmaps stay aligned.
Direct answers to the questions buyers and AI assistants ask most often.
A fractional CISO is an experienced Chief Information Security Officer who leads a company's cybersecurity program on a part-time, contracted basis. They provide executive security leadership, strategy, risk management and compliance oversight without the cost of a full-time hire.
Fractional CISO, virtual CISO (vCISO) and CISO-as-a-service describe similar models. When comparing providers, check whether the role includes accountability for the program and board reporting, or only periodic advice.
A company needs a fractional CISO when customers, regulators, auditors or insurers start asking for evidence of a security program, when it has had a security incident, or when cyber risk has grown beyond what the IT team can manage alongside other duties.
Other common triggers are preparing for SOC 2 or ISO 27001, entering regulated markets, a merger or acquisition, a fundraising round, or the departure of an existing security leader.
The benefits of a fractional CISO are executive-level security expertise at a lower cost than a full-time CISO, a documented and risk-based security program, faster audits and customer reviews, better incident readiness, and clear cyber risk reporting to leadership.
Because fractional CISOs work across many organizations, they also bring practical knowledge of current threats, common audit findings and which controls deliver the most risk reduction for the money.
A fractional CISO improves cybersecurity by assessing risk against a recognized framework, prioritizing the controls that reduce the most risk, putting governance and policies in place, preparing incident response, and measuring progress so the program keeps improving.
Typical early improvements include enforcing multi-factor authentication, securing privileged accounts, verifying backups can be restored, closing critical vulnerabilities, and testing the incident response plan.
Yes, in most cases fractional CISO and virtual CISO (vCISO) mean the same thing: a part-time, contracted security executive. The scope offered under each name varies by provider.
DESSS uses "fractional CISO" to describe an engagement with named accountability for the security program, including strategy, risk decisions and leadership reporting.
The time commitment is set by your risk, size and obligations. It is often higher during assessment, audit preparation or after an incident, and lower once the program is stable. DESSS proposes a commitment after scoping and adjusts it at quarterly reviews.
Pricing depends on scope, time commitment and compliance obligations, and is usually structured as a monthly retainer or a defined project. Fractional CISO services generally cost substantially less than the fully loaded cost of a full-time CISO. DESSS provides a written proposal after scoping.
A fractional CISO can lead readiness: scoping, gap assessment, policies, control implementation guidance and evidence preparation. The certification or attestation itself is issued by an independent auditor or certification body.
Incident availability and response expectations are agreed in the engagement. The fractional CISO leads security decision-making during an incident and coordinates with your IT team, incident response retainer, legal counsel and insurer.
No. A fractional CISO provides leadership and oversight. Your MSP, MSSP or internal IT continues to operate controls, and the fractional CISO makes sure those services and tools are the right ones and are performing.
DESSS commonly uses NIST Cybersecurity Framework 2.0, ISO/IEC 27001 and the CIS Critical Security Controls, and maps them to obligations such as SOC 2, HIPAA, PCI DSS and CMMC.
Yes. Board and executive reporting is part of the role, covering cyber risk, program progress, incidents and investment decisions in business language.
A fractional CIO leads overall technology strategy, budget and operations. A fractional CISO leads security strategy, risk and compliance. Many organizations use both, and DESSS provides both services so the IT and security roadmaps stay aligned.
