In this post, we will discuss the security testing routine for teams without a security engineer.
Most companies running a real product do not have a security engineer, and are not going to hire one this year. The salary is out of reach, the role is hard to fill, and there is rarely enough dedicated work to justify a full-time hire until the company is considerably larger. As a result, security testing often ends up owned by nobody in particular, which, in practice, means it only happens when a customer asks for it.
That is a worse position than it sounds, because the absence of a specialist does not mean the absence of a routine. A small team can cover most realistic risks with a schedule, a short checklist, and just a few hours each month.
What follows is a practical routine that works at that scale, organized by how often each task should happen.

Start by Finding Out What You Look Like from the Outside
Before building any schedule, establish a baseline. You cannot plan around risks you have not measured, and most teams have never viewed their own product the way an external attacker would.
The simplest version of this takes about five minutes. Point a web application security scanner at your primary domain and review what it reports about:
- TLS configuration
- Security headers
- Cookie flags
- Information exposed through response headers
This is only a surface-level assessment rather than a complete security review, so it will not uncover deep vulnerabilities. However, it usually identifies several issues that take only a few minutes to fix and may have gone unnoticed for months—or even years.
Document everything the scan finds. That list becomes your starting inventory, and the purpose of the routine below is to prevent those issues from quietly returning.
Every Release: The Five-Minute Checklist
The highest-value habit you can build is a short checklist that runs before every release.
The key is to keep it short. A checklist with thirty items gets ignored. A checklist with five gets used.
Did this change touch authentication or permissions?
If the answer is yes, have a second person review it before merging. Authorization issues remain one of the most damaging categories of web application vulnerabilities and are surprisingly easy to introduce during routine refactoring.
Are there new secrets in the code?
Check for:
- API keys
- Access tokens
- Connection strings
- Credentials
Most major source-code platforms now provide free secret-scanning capabilities. Enable them if you haven’t already.
Did any new endpoint become publicly accessible?
Every new endpoint increases your attack surface.
Someone on the team should be able to clearly explain:
- What the endpoint does
- Who is allowed to access it
- Whether authentication is required
Did dependencies change?
Every new dependency introduces additional code into your application.
Take a moment to verify that newly added packages are actively maintained and have no known critical security concerns.
Is sensitive information being logged?
Application logs should never contain:
- Authentication tokens
- Personal information
- Full request bodies
- Passwords
- Session identifiers
Logging sensitive data is one of the easiest ways to turn a minor security incident into a major compliance problem.
Five honest questions before each release can prevent a surprisingly large percentage of common security mistakes.
Every Week: A Short Security Review
Once each week, dedicate approximately thirty minutes to reviewing three areas.
Review Dependency Alerts
Look through your dependency alerts and actively triage them rather than letting the notification count continue to grow.
Many reported vulnerabilities may not affect the way your application uses a package, but the ones that do deserve prompt attention—not a place in the backlog.
Review Authentication Activity
Spend a few minutes looking for unusual authentication behavior, such as:
- Repeated login failures
- Logins from unexpected locations
- Tokens remaining active longer than expected
- Suspicious account activity
You are not building a full security operations center. You’re simply making a habit of occasionally checking the information already available to you.
Review Security-Related Tickets
Look through any security-related issues opened during the week.
Confirm that each issue:
- Has an owner
- Has a planned resolution date
- Has not quietly stalled
A vulnerability with no owner and no timeline is effectively a vulnerability you’ve decided to keep.
Every Month: Test the Running Application
Weekly reviews help identify gradual changes, but they cannot reveal weaknesses that only become visible when someone actively attacks the running application.
That requires testing the application while it is live.
Historically, this is where smaller organizations struggled.
Traditional penetration testing often costs between $15,000 and $50,000 per engagement and may require several weeks to schedule and complete. For smaller companies, this usually limits testing to once per year.
The problem is that products shipping updates every week accumulate dozens of releases between annual assessments. By the time a penetration testing report arrives, parts of the application may already have changed significantly.
A more practical alternative is to perform testing on a regular monthly schedule using an automated penetration testing tool, while reserving comprehensive manual assessments for major architectural changes, compliance audits, or other high-risk milestones.
More importantly, the testing cadence begins to match the actual development cadence.
Test While Logged In
One detail matters more than the choice of tool itself:
Always test authenticated areas of the application.
Unauthenticated testing primarily examines the public-facing portions of your website.
Authenticated testing reveals the issues that matter most, including:
- Broken access control
- Authorization flaws
- User-to-user data exposure
- Privilege escalation
Create two dedicated test accounts, keep their credentials current, and ensure your testing process consistently uses them.
Every Quarter: Step Back
Four times a year, set aside half a day to review the bigger security picture—things that don’t fit into a weekly routine but can significantly affect your overall security posture.
Review Access Permissions
Start by reviewing who has access to your systems.
Look for:
- Former employees or contractors who still have active accounts
- Unused service accounts
- Cloud permissions granted for temporary projects but never removed
Access reviews are rarely exciting, but they consistently uncover issues that could become serious problems during a security audit—or worse, after a breach.
Verify Your Asset Inventory
Compare your documented inventory with reality.
Make sure you know about every:
- Subdomain
- Staging environment
- Development server
- Third-party integration
Forgotten environments—especially staging systems containing production data—remain one of the most common causes of avoidable security incidents.
If nobody checks for them, nobody remembers they exist.
Test Your Backups
Do not simply confirm that backups exist.
Confirm that they actually restore successfully.
A backup that cannot be restored provides no protection when you need it most.
Reevaluate Your Priorities
Security priorities should evolve alongside your product.
If you recently introduced:
- Payment processing
- Customer portals
- Administrative dashboards
- New APIs
Those areas likely deserve more attention than parts of the application that haven’t changed in years.
Quarterly reviews help ensure your security efforts continue to focus on the areas that matter most.
On Compliance
Many teams begin thinking seriously about security only after:
- An enterprise customer requests SOC 2
- A prospect asks about GDPR
- A security questionnaire appears during procurement
There’s nothing wrong with compliance being the trigger.
The mistake is treating the certification itself as the finish line.
Most compliance frameworks can technically be satisfied with:
- An annual penetration test
- A collection of policy documents
- Security procedures are stored in a shared folder
Unfortunately, none of those things prevents the authorization bug that was introduced during last Tuesday’s deployment.
Teams that consistently build secure products treat compliance differently.
Instead of preparing for an audit once a year, they perform security activities continuously and allow certifications to become a natural by-product of an already healthy process.
The result is not only easier audits—it is a genuinely more secure product.
The Honest Summary
None of this requires a dedicated security engineer.
It simply requires treating security testing as a recurring operational activity instead of something that only happens after an incident or when a customer requests it.
If you want one question to ask at your next team meeting, make it this:
“How would we know if the code we shipped today introduced a security vulnerability?”
If the honest answer is:
- “We’ll find out during the annual penetration test.”
or
- “A customer will probably tell us.”
Then you’ve accurately described your current security posture.
Everything in this routine exists to change that answer.
Solutions designed specifically for development teams—such as penetrify.cloud—exist because annual testing no longer matches the pace at which modern software is built.
Start with a free baseline scan.
Add the five-minute checklist to every pull request.
Schedule one automated security assessment every month.
That small investment of time delivers the majority of the security value, and most teams can put the entire routine in place within a single afternoon.
