A security tool trial should usually run two to four weeks. That is long enough to scan real repositories, see at least one full sprint of findings and test an integration, but short enough that the team stays focused. Size it by what you must prove, not by the vendor's default window.
Why the default window is often wrong
Vendors pick a trial length that suits their sales process. A 7 day window can show you a clean dashboard, but it rarely shows you how the tool behaves when a developer opens a pull request on a Tuesday afternoon. A 90 day window drifts, because nobody owns the clock.
Instead, write down the questions you need answered. Each question has a minimum time cost.
| What you need to prove | Minimum time it takes |
|---|---|
| The tool scans your real code and parses your build | 1 to 3 days |
| Findings are accurate enough to trust | 1 week of triage |
| It fits the developer workflow (IDE, pull request, CI) | 1 to 2 sprints for steady use |
| Integrations with ticketing and SSO work | 2 to 4 days of setup plus a week of use |
| Support responds when something breaks | Needs a real ticket, so plan it early |
Add these up and most teams land between 14 and 28 days.
A simple way to size your trial
- List the three to five decisions the trial must support, such as "can we run this in CI without slowing builds".
- Give each decision a test and an owner.
- Add the setup days those tests need.
- Add a buffer of about 20 percent for the things that always go wrong, like access requests.
- Put the end date in a shared document and in the vendor agreement or email thread.
If the total comes out under a week, you are probably testing too little. If it comes out over six weeks, split it into two phases with a go or no go checkpoint between them.
When a shorter trial is fine
A short trial works when the tool is narrow and the risk is low. A single IDE plugin for one team, for example, can be judged in a week if ten developers use it daily. A browser extension or a command line tool with no server component has a similar profile.
When you need a longer one
Go longer when the tool will gate releases, touch production systems, or feed compliance evidence. Gates need time to produce a few blocked builds so you can see whether the blocks were correct. Compliance evidence needs at least one collection cycle, because the first run is always incomplete.
Protect the clock
Three habits keep a trial from drifting:
- Fix the start date to the day you have access, not the day the contract was signed.
- Hold a 15 minute check in at the end of week one to confirm the plan still fits.
- Decide in advance what happens at the end: decision meeting date, who attends, what evidence is on the table.
You can see how this works in practice by running a free scan before you start the clock, so day one is not spent on basics. Safeguard offers a free scan that gives you a first look at dependency findings with no setup. Related reading: what to prepare before day one.
Try it yourself
Open the demo and look at how a scan result turns into a prioritised list. That list is the thing your trial week two should be judging.

Quick check
Is a 14 day trial enough?
For a narrow tool used by a small team, yes. For anything that gates builds or feeds audit evidence, plan for 21 to 28 days or run two phases.
Should the trial clock start at signup?
No. Start it when you have working access to the repositories and systems you plan to test, and write that date down.
