The vCISO Playbook

The vCISO Playbook: How Virtual CISOs Deliver Enterprise-Grade Cybersecurity to Small and Medium Businesses (SMBs)

Protect Your Data with a vCISO Working for Your Business

The authors of this Guide have focused on two principal audiences: Small and Midsized Businesses (SMBs) and Virtual Chief Information Security Officers (vCISOs). vCISOs in this context may also be referred to as Subject Matter Experts (SMEs). By extension, we include in our audience trusted professional advisers to SMBs, such as attorneys, investment bankers, and financial consultants.

Our combined experience in cybersecurity and small business matters spans over 50 years, and we have concentrated on the intersection of the needs of SMBs with the capabilities of vCISOs. We are versed in the growing necessity of SMBs in the supply chains of critical infrastructure to demonstrate that they have taken steps to assure their ability to prevent or recover from cyber-attacks.

Note that we have included two Appendices with public source information on the DHS/CISA list of the 16 critical infrastructure sectors, as well as SMBs' participation in their supply chains. Appendix 3 sets out the features of Beta Centauri℠, our proprietary program to create an efficient working relationship between SMBs and vCISOs. In Appendix 4, we have included summaries of four articles published recently in Cyber Defense Magazine on the stages of successful relationships between SMBs and vCISOs.

Typically, SMBs have experienced a fundamental conflict between the importance of managing the risk of cyber attacks and the cost of having a full time Chief Information Security Officer (CISO).

To begin with, the basic techniques of cyber risk management can be overwhelming to owners and managers of SMBs; they are complex and tend to change quickly as new forms of attack and response develop.

According to Bank of America's most recent Small Business Report, while 71% of small businesses report that they have digitally optimized their operations over the past 12 months, only 21% have added cybersecurity measures to their businesses. Of mid-sized businesses, 90% report that cybersecurity is a threat to their business, but only 63% are keeping software up to date, 60% are investing in digital security systems, and a paltry 50% are investing in employee security training [1].

Unfortunately, the myth persists that SMBs are too small to be targets for cyber criminals. On the contrary, they are often low-hanging fruit, with a combination of lax cybersecurity measures making them subject to existential threats by such attack modes as ransomware.

According to a Microsoft report conducted by research firm Bredin, one-third of SMBs suffered a cyber attack during the past year (2024), with the average cost of each incident amounting to over $250,000.[2]

The potential adverse impact of a ransomware attack or data breach can be devastating. It has been observed that it would have a similar effect on a company in the critical infrastructure supply chain as a provider of services requiring security clearances for employees. If a vital employee suffered an identity theft incident, they would be unable to access the government secure facility to carry out their work.
