For teams shipping AI, MCP, and agents
Appsecco tests core product behavior, connected infrastructure, and AI/MCP attack surfaces together, so the coverage matches the system you actually shipped.
Fixed quote, report reading call, and one revalidation window included.

Security engagements
Our open-source security tools and training materials are used by teams worldwide — including cloud security training (949+ GitHub stars) and the MCP security lab (157+ GitHub stars).
Traditional VAPT often tests one app, one checklist, or one fixed slice of infrastructure. Modern SaaS spans web apps, APIs, cloud, identity, integrations, and now AI. The risk lives in how those layers connect.
We test those surfaces together, trace how small issues chain into real impact, and give your team evidence-backed findings they can fix without decoding the report first.
Completed assurance vs attack surface now in prod
Completed assurance
What buyers assume
The report means the risky paths were tested.
Familiar signal. In AI/MCP-enabled products, it can hide the hardest gaps.

AI, MCP, and Agent Security
Many SaaS teams did the reasonable thing: they bought the pentest, got the report, and checked the box.
Once AI, MCP, or agents are wired into the product, that old assurance model often stops proving what it looks like it proves.
Follow the gap
Step through where the checklist boundary ends and the connected product surface begins.
Stage 1
Familiar check
Authentication, RBAC, and session handling were reviewed.
Why buyers trust it
That feels like access was tested end to end.
Where coverage stops
Checklist VAPT often stops at visible login, token, and role boundaries inside the app.
What remains exposed
It may never test how prompts, shared context, tool calls, or agent permissions create new paths into internal systems.
Stage 2
Familiar check
Endpoints, inputs, and known integrations were in scope.
Why buyers trust it
That feels like the important data paths were covered.
Where coverage stops
Checklist VAPT rarely maps how retrieval, MCP resources, memory, internal APIs, and connected tools expand what the AI layer can touch.
What remains exposed
The model may still reach tenant data, internal services, or operational systems that were never exercised in the original test.
Stage 3
Familiar check
Critical actions and high-risk workflows were reviewed.
Why buyers trust it
That feels like dangerous behavior would have been caught.
Where coverage stops
Audit-driven testing often checks that actions exist, not whether AI or agent flows can trigger them out of sequence or across trust boundaries.
What remains exposed
An attacker may still be able to invoke tools, chain actions, poison context, or escalate privileges in ways the report never attempted to simulate.

Our AI security work is grounded in hands-on research and labs because the public guidance is still early, including the Appsecco vulnerable MCP servers lab. View the lab
Testing scope
Appsecco tests the connected product system: core product behavior, the infrastructure it depends on, and the AI / MCP layer added on top.

See detailsWhat You Get
After the engagement, your team works from clear findings for security, clear fix guidance for developers, and extra documentation when customers, compliance teams, or partners ask for it.
The report is the anchor artifact. When needed, Appsecco also produces evidence packages for internal review, revalidation, and external documentation.
The report is the working artifact for triage, remediation, and follow-through: the issues that matter, the evidence behind them, and the fix guidance your team needs to act.
Leadership brief
Risk themes · priorities · next actions
Give leadership the risks, decisions, and next actions without sending them through the full technical report.
Coverage worksheet
Test case · status · notes
Show reviewers what was exercised so follow-up validation or internal sign-off does not start from scratch.
Version-bound verification
Build, date, closure
Confirm a specific version was retested and the agreed fixes were verified for customers, auditors, or partners.
Submission pack
Requirements mapped
Handle regulator, marketplace, procurement, or partner documentation without building the package yourself after the test.
The Process
A clear process from first call to revalidation. You know the scope, price, delivery date, and what happens after the report.
We start with a short conversation about the product, your main concerns, and whether a deeper scoping discussion is needed.
What happens
A quick intro call sets context. If the product or environment is more involved, that call rolls naturally into deeper discovery.
What you do
Share the product shape, what matters most right now, and anything already tested.
What we do
Ask the scoping questions that affect coverage, access, timing, and quote accuracy.
What comes next
We turn the conversation into a written scope and fixed quote.
Within 48 hours, you get the engagement shape in writing: what we will test, what it costs, and when report delivery happens.
What happens
We convert discovery into a scoped engagement with a fixed quote rather than open-ended hourly work.
What you do
Review the proposed scope and confirm the product surfaces, environment, and timing are right.
What we do
Send the written scope, fixed price, and confirmed report delivery date.
What comes next
Once the scope is agreed, we lock the test window and access plan.
Before testing begins, we confirm the dates, point of contact, and the staging or scoped production access we will use.
What happens
The engagement is scheduled and the operational setup is finalized before work starts.
What you do
Provide the agreed access, test accounts, allowlisting, and a responsive contact if we need clarification during the window.
What we do
Confirm the test window, validate access, and make sure the engagement can run cleanly without surprises mid-stream.
What comes next
Once access is ready, testing runs in the agreed window.
Testing runs in the agreed window, then your team gets the report, walkthrough, and invoice. Net 7 is the default today.
What happens
We test independently, document findings, prepare the report, and walk your team through the results.
What you do
Stay available for occasional clarifications, then review the report and walkthrough with the right internal stakeholders.
What we do
Run the engagement, deliver the findings and fix guidance, answer questions, and send the invoice after the report is handed over.
What comes next
Your team fixes what matters, then comes back when the changes are ready for revalidation.
When your team says the fixes are ready, we schedule revalidation and confirm what is closed.
What happens
Revalidation happens after your remediation work, not on an arbitrary date that forces your team to rush.
What you do
Tell us which fixes are ready, share the updated build or environment, and coordinate the retest window.
What we do
Retest the agreed fixes, verify closure, and provide the updated evidence your team needs.
What comes next
You leave with confirmed closure and version-bound proof when the situation calls for it.
Pricing
Start with core product coverage, add connected infrastructure when needed, or scope AI and MCP on their own.
Core product
For the main product surface, with a baseline cloud exposure review.
Connected infrastructure
For deeper connected-system coverage when infrastructure risk is part of the real attack surface.
AI / MCP layer
For products that need AI or MCP tested on their own, or as part of a wider engagement.
These can be scoped together or independently.
What Clients Say
Teams that build security products trust us to test their own systems because the findings are clear and the process stays predictable.
Select customers shown with permission. Additional references available under NDA.
The kind of vulnerabilities they found were things we never expected — things which were not on our radar. That changed how we think about our own attack surface.
Found multiple interesting exploitable vulnerabilities across our product. Clear reporting, thorough walkthroughs of each finding, and they stayed engaged until every issue was resolved.
We engaged with Appsecco for red teaming. Their findings were specific, well-documented, and gave our team a clear path to remediation.
Want to speak with a past client in your industry? We can arrange a reference call under NDA.
When you are ready
