For SaaS teams shipping AI, MCP, and agents

Security testing for SaaS products that ship 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.

Request scoped assessment See MCP server testing

MCP servers

AI/MCP builders start here

Start with tool, data, and auth boundaries

For assistants, agents, and MCP servers that call tools, reach APIs, read files, or touch tenant data.

Scoped by

MCP servers, tools, transports, auth flows, tenant boundaries, and connected resources.

Scope MCP testing See MCP server testing

Apps & APIs

Start with product behavior and authorization paths

For app logic, API trust boundaries, tenant isolation, and multi-role workflows inside the product.

Scope apps & APIs See apps & APIs testing

Cloud, Kubernetes & IAM

Start from the trust boundary and privilege model

For cloud identity, Kubernetes separation, exposed services, storage risk, and chained escalation paths.

Scope cloud & IAM See cloud, Kubernetes & IAM testing

If more than one surface matters, start with the path that can create the highest-impact action. We combine the rest during scoping.

AI, MCP, and Agent Security

You passed the VAPT. The new attack surface may never have been tested.

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.

You can pass checklist or compliance VAPT and still leave the most important AI/MCP attack paths untested.

Follow the gap

Step through where the checklist boundary ends and the connected product surface begins.

Stage 1

Who Can Access

Checklist -> Gap

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

What Can Be Reached

Checklist -> Gap

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

What Can Be Done

Checklist -> Gap

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.

Testing scope

What Appsecco tests that ordinary VAPT usually misses

Appsecco tests the connected product system: core product behavior, the infrastructure it depends on, and the AI / MCP layer added on top.

Coverage view

Start with the product surfaces every SaaS team recognizes: application behavior, APIs, data boundaries, and authentication.

Authz / tenancy

Tenant isolation, role boundaries, and the cross-account access paths that let one customer reach another customer's data.

API abuse

Method confusion, under-validated endpoints, hidden routes, and protocol edge cases that turn normal API behavior into attacker leverage.

Workflow logic

Multi-step product flows, state changes, and feature misuse paths that scanners and checklist testing usually flatten into isolated checks.

Before you commit

Inspect the report standard, research trail, and review package before the first call

The fastest way to judge a security testing practice is to review what it publishes, what the report looks like, and how clearly it explains the artifacts your team will carry into engineering, security, and buyer review.

Sample report

The report is designed for engineering review, not just procurement

Before any engagement, you can inspect the same evidence standard we use in client work: scoped findings, attack-path narrative, remediation guidance, and supporting artifacts that stand up in internal review.

Executive summary tied to decisions, not only severity labels
Attack-path narrative that shows how issues combine into real risk
Remediation guidance your engineers can act on without translation
Artifacts that make revalidation and customer review easier

Public research

The practice publishes real tooling, not only service copy

Appsecco's research footprint is visible before the first call. That matters because buyers should not have to infer technical depth from generic marketing language.

What your team gets

The deliverable system is built for triage, remediation, and proof

Buyers usually need more than a PDF. They need evidence that can move between engineering, security, and review stakeholders without losing context.

Executive summary

Risk themes, business impact, and the decisions leadership should make first.

Evidence-backed findings

Reproduction steps, impact notes, and supporting artifacts tied to the real attack path.

Fix guidance

Practical remediation direction with enough specificity for engineering follow-through.

Revalidation proof

A clear record of what was retested when customers, auditors, or launch reviewers ask for closure.

Additional references are available under NDA when the buying process calls for them.

From a B2B SaaS engagement

"We thought our automation had us covered. The manual testing didn't replace it — it showed us the categories of issues that automation isn't built for. Now we run both."
