AI Prompt Injection Defense
Adds input and output defences against prompt injection in your AI apps.
Every pull request, config change or new integration is reviewed for security issues as it happens, before it merges.
Security problems are cheapest to fix before code merges, but busy reviewers miss things. This assistant reads each pull request, config change and new integration as it is opened, checks it against the rules you approve, and posts findings right on the change with severity and a suggested fix. Your reviewers still decide what merges. Nothing is blocked without a person.

AI Security Review Assistant reviews proposed designs, architecture changes and new integrations for security risk, using a simple threat model for each. It also checks the security-relevant pull requests and configuration changes that follow. Findings are ranked by severity, with guidance your team can act on. It does not scan whole codebases or review general code quality.
A security flaw caught in review costs a short conversation. The same flaw found in production can mean an incident, a customer email and a week of cleanup. Most teams know this, but reviewers are stretched and focus on whether the code works. This assistant adds a steady second look at every risky change, in the place your team already reviews. The written scope tells you which repositories, which change types and how many rules are covered before you commit.
The assistant reviews each pull request, configuration change and new integration as it is proposed. Problems can be fixed before they ever reach the main branch.
Routine security checks happen automatically on each change. Senior staff can focus on complex reviews instead of reading every diff for the same common issues.
Configuration changes and new integrations are reviewed alongside code. A risky setting is flagged on the change itself, where its author will see it straight away.
Each finding lands on the change, ranked by severity, with guidance developers can act on. They know what to change and why before they merge.
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
| Option | Delivery time | Price |
|---|---|---|
| Standard | 20–30 working days | $4,400 |
| Express | 15–25 working days | $5,150 |
| Rush | 10–20 working days | $5,950 |
Before you start: Record recent post-release security bugs and the average pull request review time.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
The build price is one-time. Running the review assistant costs roughly $20 to $300 a month in your own accounts, for hosting, logging and the monitoring tools it relies on day to day.
AI model usage during the build and testing is billed the same way, directly to your accounts, so you keep ownership of every provider relationship involved.
Ask about running costsIf you need something outside the Scope Card, such as review coverage across more than three repositories or systems, add a note at checkout. You get a written Change Quote, and that work only starts once you accept it. Larger or bespoke projects go through the Custom AI request form instead.
Request a custom versionMonthly maintenance covers monitoring and change hours for work such as tuning which changes trigger review or adding a repository. It starts after the 30 days of included support and can be cancelled any month.
$249/mo (the minimum fee, includes 2 change hours)
Optional. Starts after the post-launch support period. Cancel any month.
How maintenance works| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A code review bot charges per seat or per repository, monthly | A security firm quotes after a scoping call | Ours is one fixed price, shown on this page before you buy |
| Scope | A code review bot applies one generic rule set to everything | An agency agrees scope during the engagement | Ours is written on the Scope Card, up to 3 systems |
| Delivery | A code review bot still needs configuration before it is useful | A security firm engagement often takes weeks to schedule | Ours has a fixed delivery time shown before you buy, with faster options |
| Trigger | A code review bot may review every commit indiscriminately | An agency reviews on its own delivery schedule | Ours reviews the pull requests and changes that matter to you |
| Certification | A code review bot does not certify anything on its own | An agency may offer certification as a separate service | Ours is a review and monitoring workflow; no certification is implied |
It reviews proposed designs, architecture changes, new integrations and the security-relevant pull requests or configuration changes that follow. Each is checked against a simple threat model and the rules you approved. Findings post on the change or design document, plus a rollup to Slack or Jira, so reviewers see each concern in context.
This assistant reviews designs, architecture changes and new integrations against a threat model, plus the security-relevant changes that follow. AI Application Security Agent scans your code and dependencies on a schedule. AI Code Review Agent reviews every pull request for bugs and standards. Many teams pair design review here with scanning from the agent.
Running costs are small and paid in your own accounts: roughly $20 to $300 a month for hosting, logging and the monitoring tools the assistant depends on. The figure stays fairly flat however many pull requests your team opens. We charge nothing per review. The one-time build price, at each delivery speed, is shown in the price panel on this page.
No. It flags concerns with severity and an explanation on the pull request itself, and a person on your team decides whether to merge, fix or discuss it further. We do not give it authority to block or approve changes without a human somewhere in that loop. The goal is to inform your existing review process, not replace the judgment of your reviewers.
Reviews run automatically as soon as a matching pull request or configuration change is opened, typically within minutes, so findings are available before your own team finishes its usual review pass rather than arriving later as a delayed, disconnected report. That speed means findings inform the same review cycle your team already runs, not a separate one.
Yes. Adjusting which repositories, branches or change types trigger a review fits inside the monthly change hours that come with maintenance. Adding review coverage across more systems than the three included in scope comes through a Change Quote, priced and agreed with you before that work starts. This keeps the assistant useful as your codebase and your team's priorities shift over time.
You do. The review rules, the repository connections and the history of flagged changes all live in your own accounts and tools, such as your GitHub, GitLab, Slack or Jira, not a separate platform we control or hold you to. We keep no separate copy that would lock you into working with us going forward.
