Security testing guides

Practical guides for buying, scoping, and reviewing product, cloud, and AI security testing without guesswork.

Written to help engineering and security teams make clearer buying decisions before a test starts.

Use the right guide for the decision in front of you

Different security-testing questions need different kinds of help. Some teams need a calm introduction to what a pentest looks like. Others need a concrete buyer checklist for MCP servers, or a way to explain how AI red teaming fits into broader product security work.

This hub groups those resources by the job they do: preparing for a purchase, evaluating specialist scope, and reviewing the proof or deliverables that make an engagement defensible inside engineering, security, and procurement.

Why the guides are trustworthy

These buyer guides come from the same operator trail teams inspect before they scope work

The point is not to publish generic content. It is to make the underlying method, public research, and reporting standard easier to review before a security team commits to specialist testing.

  • Written by the practice behind the public MCP checklist, lab, and client-side testing tools
  • Grounded in the same report artifacts and scope language buyers use in internal review
  • Designed to reduce ambiguity before procurement, engineering, and security stakeholders start comparing vendors

Start with the proof behind the guides

Public proof buyers can inspect before they scope work.

If you want to inspect the practice behind these guides, these are the public and buyer-facing assets most teams open first.

Sample Report

Inspect the evidence format, reproduction steps, and remediation detail before you ask for a quote.

Methodology

See how Appsecco scopes, runs, and delivers product security testing engagements.

MCP Security Testing Checklist for Buyers

Review the public checklist for tool safety, auth, connected-resource risk, and reporting depth.

Vulnerable MCP Servers Lab

A public training lab that makes tool abuse, prompt injection, and boundary failures concrete.

If you need the closest proof path or commercial route next, start there instead of opening a generic contact thread.

Buyer guides

Start here if you are buying or scoping testing

These are the practical guides for first-time buyers, procurement-heavy workflows, and teams trying to turn a vague testing request into a fixed, reviewable scope.

Buying basics

Your First Penetration Test

A calm walkthrough of scope, safety, communication, reporting, and what a good pentest process should feel like.

Best when your team needs shared language before talking to vendors.

Read guide
Vendor evaluation

Pentest RFP Template

A buyer-focused template for standardizing proposals, comparing vendors fairly, and making testing scope explicit in writing.

Best when procurement or multiple vendor bids are part of the process.

Read guide
Specialist scope

MCP Security Testing Checklist for Buyers

A checklist for evaluating whether an MCP assessment really covers transports, tools, prompt-to-tool risk, connected resources, OAuth, and report quality.

Best when AI assistants can reach tools, internal APIs, databases, or file systems through MCP.

Read guide

AI & MCP depth

Use these when the AI layer changes the risk

These guides help when the problem is not just app security, but model behavior, tool access, prompt-driven actions, and the difference between red teaming and broader product-security scope.

Scope design

AI Red Teaming for LLM Applications

How to think about adversarial testing for LLM apps, RAG workflows, tools, MCP-backed actions, and model-connected product behavior.

Best when you need to separate behavior-risk testing from infrastructure or app-control review.

Read guide
Decision support

AI Red Teaming vs AI Security Testing

A side-by-side explanation of where red teaming fits, where product-security testing still matters, and why mature AI launches often need both.

Best when stakeholders are using the same terms to mean different types of testing.

Read guide
Boundary clarity

AI Agent Security Testing vs MCP Security Testing

A buyer-facing guide for separating workflow-level agent risk from protocol-level MCP, tool, and connected-resource risk.

Best when your AI feature uses agents and MCP, and reviewers are not sure where the real risk begins.

How to use the guides without getting lost in content

The goal is not to read everything. Pick the guide that matches the current decision, then use it to tighten scope, compare options, or prepare internal reviewers before a statement of work is signed.

Start with the buying question

Use the first-pentest or RFP material when the team is still deciding how to buy testing at all.

Switch to specialist scope when the surface changes

Use the MCP and AI guides when tools, prompts, model behavior, or connected resources create risk that generic pentest language hides.

Cross-check the evidence standard

Use the guides alongside the sample report, methodology, and service pages to confirm the deliverables and testing approach are concrete.

Turn the result into a fixed next step

Once the buying question is clear, move into a scoped assessment conversation or an RFP with less ambiguity and less internal churn.

The guides should help you answer

What type of testing actually matches the surface we are shipping
What a defensible scope and report should contain before work starts
Which next step reduces uncertainty instead of adding more process

Use these alongside the guides

Sample Report

Inspect the evidence, reproduction style, and remediation format before asking for a quote.

Methodology

See how Appsecco scopes, runs, and delivers product security testing work.

Security Testing Glossary

Reference terms for AI, application, cloud, IAM, prompt injection, and MCP security concepts.

Pricing

Guides FAQ

Which guide should we start with if we are shipping MCP servers?

Start with the MCP Security Testing Checklist for Buyers if the immediate question is how to evaluate scope and vendor depth. If your broader team is still aligning on how MCP, agents, and AI security testing relate, the agent-versus-MCP and AI red teaming comparison guides are the next useful reads.

Do these guides replace a scoping conversation?

No. They help remove ambiguity before a scoping conversation starts, which makes the eventual discussion shorter, clearer, and easier to defend internally.

Can we use these even if we are not working with Appsecco?

Yes. They are written as buyer resources first. The point is to help teams ask sharper questions, define safer scope, and know what good evidence should look like regardless of vendor.

What if we need both general product testing and AI or MCP-specific depth?

That is common. Use the guides to separate the surfaces and then scope them together deliberately, rather than letting specialist work get flattened into a generic pentest statement of work.

Safe next step

Need help choosing the right guideor the right test?

Share the product surface you are shipping, what it can reach, and what kind of evidence your reviewers expect. We will point you to the right guide first, then talk scope only if it is useful.
