Top Security Consulting Companies

Q: What does a security consulting firm do?

A security consulting firm assesses an organization's risks and controls and builds the program to fix the gaps. Work includes risk assessments, ISO 27001 and SOC 2 readiness, policies, incident response plans, virtual CISO services, and physical site assessments and security system design.

Q: How much does a security consultant cost?

Assessments are usually fixed fee, virtual CISO work is a monthly retainer, and tests or site reviews are priced per target or location. Most consultants on this page set no minimum or a minimum of $1,000 to $5,000, and some start at $100,000 or $250,000 for enterprise programs.

Q: When does a company need a virtual CISO?

A virtual CISO fits when customers, investors or regulators expect a security program but the company is not ready for a full-time security executive. The consultant owns the roadmap, policies, risk register and audit preparation for a set number of days each month.

Q: What is the difference between security consulting and managed security services?

Security consultants assess, design and advise, then hand the plan to your team. Managed security services providers operate controls every day, such as monitoring, threat detection and response, and firewall management. Many companies hire a consultant first to define what a managed provider should run.

Q: Which industries hire security consultants?

Security consultants listed here most often serve financial services firms, information technology companies, healthcare providers, business services, government agencies, ecommerce sellers and manufacturers. Finance, healthcare and government buyers face the strictest audit and compliance demands.

Q: Where are most security consulting firms based?

The security consultants on this page are listed most often in Toronto, Los Angeles, Vancouver, Austin and Bengaluru. Information security work runs largely remotely, while physical site assessments need a consultant who can travel to each location.

An enterprise customer sends a security questionnaire, an auditor wants evidence of controls, or a facility needs to pass a government security review: these are the moments companies bring in security consulting firms. Consultants assess risk, write policies, prepare organizations for ISO 27001, SOC 2 or a facility clearance, act as a part-time CISO, and on the physical side assess and design protection for buildings and people.

When comparing the security consultants here, check whether their strength is information security, physical security or both, the certifications their staff hold, and whether they also sell the tools they recommend.

Buyer's guide

Hiring Security Consulting companies

What the work covers, how to judge a partner and what drives the price.

What security consultants do

Information security consulting covers risk assessments against frameworks such as ISO 27001, the NIST Cybersecurity Framework and CIS Controls, gap analysis and readiness for SOC 2 or ISO certification, written policies and incident response plans, vendor risk reviews, and virtual CISO services where a senior consultant runs the program part time. Many firms also coordinate penetration tests and security awareness training.

Physical security consulting covers threat and vulnerability assessments of sites, crime prevention through environmental design, specifications for cameras, access control and barriers that installers then bid on, security operations procedures, and support for defense contractors managing facility clearances and a facility security officer role.

Engagements start with scoping and interviews, move to evidence collection and testing, and close with a prioritized remediation roadmap. Ongoing retainers then track progress and audit readiness.
