A security audit costs $3,000 to $50,000 depending on what’s reviewed and who does the reviewing. The internal, do-it-with-a-consultant version runs $3,000 to $10,000. A third-party compliance audit runs $10,000 to $50,000 or more, and a certification-grade engagement like SOC 2 Type 2 carries an audit fee of $30,000 to $70,000 for a typical SMB before you count remediation. Same word, “audit,” three very different purchases. This post sorts them out.
We’re gmware, a custom software development firm headquartered in Austin, TX with engineering centers in Bangalore and Mohali, India. We build and run production systems ourselves, including Shield Suite, a retail-intelligence product covering 60,000+ beverage-alcohol storefronts, so audit findings land on our own desks too. Below: what a security audit actually covers, cost by audit type, how an audit differs from a penetration test, what a real report contains, and the honest call on when a self-assessment is all you need.
Security audit cost at a glance
What does a security audit actually cover?
Six areas, whether the auditor says so up front or not. A serious audit reviews security governance, network security, access control and identity management, vulnerability management, data protection, and incident response. Here’s what each one looks like when it’s your Tuesday getting audited.
Policies and governance. The auditor asks for your written security policies: acceptable use, access management, vendor risk, incident response. Then they check whether anyone follows them. A policy last touched in 2021 that names an employee who left in 2023 is a finding, and a common one.
Access review. Who can log into what, and should they? Expect the auditor to pull your user lists, admin accounts, and permission grants, then hunt for the classics: the contractor whose account outlived the contract, the shared login for the billing system, the intern with domain admin. Most audits find their ugliest results here.
Configuration review. Firewall rules, cloud settings, endpoint hardening, backup jobs. Not “is the software patched” so much as “is the software set up the way the vendor and the framework say it should be.” An S3 bucket open to the internet is a configuration finding, and it’s the kind a policy review alone never catches.
Vulnerability assessment. An automated scan of your systems against a database of known weaknesses, priced at $1,000 to $5,000 as a standalone. Inside an audit, it’s the evidence layer: the scan output tells the auditor whether your patching policy is a document or a practice.
Compliance-gap mapping. Your controls, lined up against whatever framework you answer to: SOC 2, ISO 27001, HIPAA, PCI-DSS, or a customer’s security questionnaire. A standalone gap analysis runs $3,000 to $12,000 and it’s the piece buyers most often ask for by name.
Incident readiness. Do you have a plan, has anyone rehearsed it, and would the backups actually restore? The auditor doesn’t set anything on fire. They check whether you could put one out.
Security audit cost by type
There’s no single audit price because “audit” covers at least six distinct engagements. Here’s what each one costs on current market pricing, from cheapest to most expensive.
| Audit type | What it is | Typical cost |
|---|---|---|
| Vulnerability assessment | Automated scan for known weaknesses, reported | $1,000 to $5,000 |
| Policy and control review | Your written policies and controls, read and verified | $2,000 to $10,000 |
| Internal security audit | Full internal review, self-run or consultant-guided | $3,000 to $10,000 |
| Compliance gap analysis | Controls mapped against one framework, gaps listed | $3,000 to $12,000 |
| Cloud security audit | IAM, storage exposure, config in AWS, Azure, GCP | $3,000 to $15,000 |
| Third-party compliance audit | Independent audit against SOC 2, ISO 27001, HIPAA | $10,000 to $50,000+ |
| SOC 2 Type 2 (audit fee) | Certification-grade audit over a 3 to 12 month window | $30,000 to $70,000 for SMBs |
Size scales the number inside each band. An internal audit runs $5,000 to $15,000 for a small business and $15,000 to $40,000 for a mid-market company, mostly because there are more systems, more users, and more evidence to collect, not because the work is different in kind. Budget one more line while you’re at it: certification audits repeat, and annual re-audits typically run 70 to 80 percent of the initial audit cost.

Security audit vs penetration test: breadth vs depth
An audit reviews everything a little; a pentest attacks one thing hard. The audit reads your policies, pulls your access lists, checks your configurations, and maps the gaps. It answers “where is our program weak?” A penetration test puts a skilled human against a scoped target to chain weaknesses and prove exploitability. It answers “could someone actually get in, and what would it cost us?”
The two get confused because cheap vendors blur them on purpose. A quote that says “security audit” but only includes a scan, or one that says “penetration test” at a price under about $3,000, is almost certainly automated scanning, not manual work. Read the deliverable, not the title.
Sequence matters more than either purchase. Run the audit first. It’s cheaper per finding, and it catches the open buckets and orphaned admin accounts a pentester would burn expensive hours rediscovering. Then point the pentest at whatever the audit says is your crown jewel. We priced the pentest side in detail, type by type, in our penetration testing cost guide.
Internal, third-party, or compliance-driven: which audit counts?
Depends entirely on who needs to believe the result.
Internal audit. You or a consultant working for you, reviewing your own environment. It finds most of the same gaps a third-party audit finds, at the bottom of the price range. Its one limit is credibility: nobody outside your company will accept it as proof, for the same reason nobody accepts self-graded exams.
Third-party audit. An independent firm reviews your environment and signs its name to the findings. This is what a customer’s procurement team means when the questionnaire asks “have you had an independent security assessment in the last 12 months?” It costs more because you’re buying the signature as much as the work.
Compliance-driven audit. A third-party audit conducted against a named framework by an accredited auditor, ending in a report or certificate you can hand to buyers: SOC 2, ISO 27001, HIPAA. These are the expensive ones, and usually the ones with a deadline attached, because a deal is waiting on the report. If SOC 2 is the framework in question, we laid out the whole sequence in our 90-day SOC 2 plan, and a readiness assessment beforehand runs $5,000 to $25,000, which is cheap against failing the real audit.
One more driver sneaks up on people: insurance. Cyber policies increasingly demand evidence of specific controls before they’ll bind coverage, and an audit is how you prove them. We’ve mapped what insurers actually check if that’s the pressure you’re under.
Match the audit to the trigger
Six situations account for most audit purchases we see. Find your row.
| Your situation | What to buy | Budget from the table above |
|---|---|---|
| No external pressure, never assessed anything | Internal audit or guided self-assessment | $3K to $10K |
| Customer questionnaire asks for an independent assessment | Third-party security audit | $10K to $50K+ |
| A deal is blocked on SOC 2 or ISO 27001 | Gap analysis, then the certification audit | $3K to $12K, then $30K+ |
| Just finished a cloud migration | Cloud security audit | $3K to $15K |
| Insurer wants proof of controls | Policy and control review scoped to the application | $2K to $10K |
| Buyer or auditor demands a pentest report | Penetration test, not an audit | See the pentest cost breakdown |
The pattern worth noticing: the trigger is almost never “we got curious about our security.” It’s a questionnaire, a framework, a renewal, or a migration. That’s fine. The externally-forced audit finds the same holes the voluntary one would have.
What a security audit report should contain
Four sections, and you should refuse to accept fewer.
Scope inventory. What was reviewed, what wasn’t, and during what window. This matters later, when someone asks whether the audit covered the system that just had an incident.
Findings ranked by risk. Each gap, with a severity that reflects real-world impact on your business, not just a CVSS number copied from a scanner. Two hundred unranked findings is a data dump wearing an audit’s clothes.
Evidence. The specific policy clause, config setting, screenshot, or account list behind each finding, so your team can reproduce it instead of debating it.
A remediation roadmap. What to fix first, who should own it, and roughly what it takes. Here’s the opinion we’ll defend: the roadmap is the product. The findings expire the day someone changes a firewall rule; the prioritized plan is what actually changes your posture. An audit that ends at the findings list has sold you the diagnosis and kept the prescription.
The four sections a real report has
On timing: plan for 3 weeks for a focused assessment up to 3 months for a full enterprise audit. Your paperwork is the lever you control. Teams with current documentation cut audit timelines by 30 to 40 percent, because the auditor verifies instead of excavates.
When is a self-assessment or a scan enough?
More often than audit vendors admit. Skip the paid audit, for now, if all of these are true: nobody external is asking for proof, you run a small and fairly standard stack, and you’ve never done a first pass of any kind. In that spot, a $1,000 to $5,000 vulnerability scan plus a weekend spent honestly working through a framework checklist will surface most of what a $15,000 engagement would, because early-stage findings are rarely subtle. Expired accounts, missing MFA, no tested backups. You don’t need an auditor’s signature to fix those.
You’ve outgrown the self-assessment the moment any one of these lands: a customer questionnaire that asks for independent evidence, a compliance framework with a deadline, a cyber-insurance application, handling regulated data like payments or health records, or a stack complex enough that you’re no longer sure what’s exposed. From there, self-graded homework stops being cheap and starts being a deal blocker. Buy the audit that matches the trigger, and treat the self-assessment as prep that makes the paid engagement faster.
How gmware approaches security audits
We’re engineers who run production systems, not an audit mill selling findings by the kilogram. So we weight the engagement toward the part most audit firms hand off: the fixing. Our cybersecurity practice does the audit and then closes the roadmap: the IAM cleanup, the config hardening, the policy rewrites, the backup tests. Austin leads scope and run the engagement on US hours; our Bangalore and Mohali teams clear the remediation backlog without US-only rates. If what you actually need is ongoing security ownership rather than a point-in-time review, that’s a different purchase, and we compared the two in our cybersecurity consulting guide.
We’ll also tell you when not to hire us. If nobody’s asking for proof and you’ve never done a first pass, start with the scan and the checklist. Spend the audit budget after the cheap findings are closed.
Tell us what’s driving the question: a questionnaire, a framework deadline, an insurance renewal, or a genuine worry. Reach out and we’ll give you a straight answer on which audit you need, what it’ll cost, and how long it’ll take, within 48 hours.
