1. Nobody Owns Security
When a cybersecurity question comes up in your organization, who handles it? If the answer is "whoever is available," "our IT person, sort of," or "I guess me?" — you have a problem. Security without ownership is security without accountability. Policies don't get written because nobody is responsible for writing them. Vulnerabilities don't get addressed because nobody is tracking them. Incidents don't get reported properly because nobody knows the procedure.
This is the most fundamental sign. Every other issue on this list stems from this one. When nobody owns security, security decisions either don't get made or get made by people without the context to make them well. A vCISO provides that ownership — a named person whose specific responsibility is your organization's security posture.
