Ask for a security review early, with a one page brief that says what you are building, what is new or sensitive about it, which specific questions you have, and when you need an answer. Small, specific requests get faster replies than a late request to "review everything".
Why timing matters
A review at design time costs a conversation. A review the week before release costs a delay, and sometimes a redesign. Reviewers also treat late requests as emergencies, which leaves less time for careful reading. Asking early is a favour to yourself.
Know what is worth reviewing
Not every change needs one. A short list of triggers helps, and it keeps the reviewer's queue manageable. Common triggers:
- New handling of sensitive or regulated data
- New authentication, authorisation or session logic
- A new public endpoint or integration with a third party
- A new dependency that does something important, such as parsing, crypto or file handling
- A change to how secrets or keys are stored
If none apply, a normal code review is usually enough.
The one page brief
| Section | What to write |
|---|---|
| Summary | What you are building in two sentences |
| Why it is sensitive | Data touched, who can reach it, what is new |
| Diagram | A rough sketch of components and data flow |
| Your questions | Two or three specific things you want checked |
| What you have done | Controls you already planned, tests, scans |
| Deadline | When you need an answer and why |
Specific questions are the key. "Is it safe?" cannot be answered. "Is our token expiry and storage approach acceptable for a mobile client?" can.
Make the reviewer's job easy
Give access to the design doc or code branch. Name a person who can answer questions the same day. Share the diagram first, since a picture often settles half the questions. Tell the reviewer what you consider out of scope, so they do not spend time there.
Agree on what happens next
Ask the reviewer to label findings as blocking or advisory, and to give an expected turnaround. If a blocking finding appears, agree on who decides how to resolve it and by when. Write down any accepted risks, with the owner and a review date.
Keep it small and regular
Teams that book short, regular review slots, perhaps thirty minutes weekly, tend to resolve issues before they grow. Compare this with a quarterly big review that produces a long list of late surprises.
Handle disagreement
If you disagree with a finding, reply with facts and a question rather than a refusal, as you would with any technical review. If the disagreement stays, escalate with a one page options memo and let the accountable owner decide.
What the reviewer can do to help
If you are on the security side of this, publish your triggers, your turnaround time and a template. Tell people what you will not review. Clear rules reduce both late requests and unnecessary ones.
Safeguard's pull request gates and dependency scanning handle routine checks automatically, which leaves human reviewers for the design questions. The free scan at gold.safeguard.sh/scan shows what the automatic part looks like.
Quick check
When is a security review not needed?
When the change touches none of your trigger areas. A normal code review plus automated checks usually covers it.
How much notice should I give a reviewer?
As early as design time, and at least a few working days before you need an answer for small items.
