The short answer

What is penetration testing as a service?

Penetration testing as a service (PTaaS) is a way of buying and running manual penetration tests on a platform instead of ending each test with a single PDF. Findings appear as testers confirm them, flow into your ticketing system and are retested once fixed, so testing can follow every major release.

Some PTaaS offerings are mostly automated scanning with a portal. At ioSENTRIX, people do the testing: testers holding certifications such as OSCP and OSWE look for the business logic and authorization flaws scanners miss, and the person who found each issue walks your team through it. ioSENTRIX is a CREST-accredited penetration testing firm.

You need PTaaS if

You ship major releases more often than you pentest
Customers or auditors ask for a recent pentest report
Your engineers want findings in JIRA, not in a PDF weeks later
You want to buy testing in small blocks instead of one large engagement

What we test

Every surface you ship, on one platform

Credits work across test types, so you can point testing at whatever changed.

Apps

Web apps & APIs

Authenticated testing of the applications and APIs your customers use.

Authorization and tenant isolation
Business logic and workflows
REST and GraphQL APIs
Session and authentication flows

Clients

Mobile & thick client

Client apps and the backends they talk to.

iOS and Android apps
Desktop and thick-client apps
Local data storage
Client-to-API trust

Infra

Cloud & network

The infrastructure your apps run on.

External network perimeter
Internal network
AWS, Azure and GCP configuration
Segmentation testing

Release

Release & retest

Testing tied to how you ship.

A pentest for each major release
Targeted tests of new features
Retests of fixed findings
Annual or twice-yearly full test

Methodology

How we test: example test cases

A sample of manual test cases from typical PTaaS engagements. Your scope decides the full list.

API1:2023

Object-level authorization

We change object IDs in API calls to see whether one user can read or edit another user's records.

API5:2023

Function-level authorization

We call admin and internal endpoints with a standard user's token to test whether role checks are enforced on the server.

A01:2025

Cross-tenant access

Signed in to one tenant, we try to reach another tenant's data through URLs, exports, search and background jobs.

API6:2023

Business flow abuse

We test whether flows such as sign-up, checkout or invites can be automated or replayed in ways the business did not intend.

A07:2025

Account takeover paths

We test password reset, MFA enrollment, token lifetime and logout for ways to take over another user's account.

NET-01

Segmentation controls

Where segmentation isolates a sensitive environment, such as a PCI DSS cardholder data environment, we test from out-of-scope networks to confirm it holds.

Sample finding

What a finding looks like in our report

An illustrative example in our report format. Not client data.

Finding 01 · IllustrativeHigh

Changing an invoice ID in the API returns another customer's billing data

OWASP API1:2023 Broken Object Level Authorization · A01:2025 Broken Access Control

What we found

The billing API took an invoice ID from the request and returned the invoice without checking that it belonged to the caller's account. IDs were sequential, so any signed-in user could step through them and download other customers' invoices, including names, addresses and billing details.

Impact

Any customer could read every other customer's billing history.

How to fix it

Check ownership on the server for every object request, using the account from the session rather than the request. Use non-sequential identifiers as defense in depth, and add an automated test for cross-account access.

What you get

What you get from PTaaS

Not a PDF that arrives after the sprint ends. Findings your engineers can act on while the code is fresh.

Real-time findings in JIRA

Findings appear on the platform as testers confirm them and can be pushed to JIRA, so fixes start before the test ends.

Proof and a fix for every finding

Each finding has a severity, a reproducible proof of concept and remediation guidance, mapped to the OWASP standards your customers ask about.

Walkthrough and retesting

The tester who found each issue walks your team through it, and fixes are retested to confirm they hold.

Scope and price

PTaaS pricing: what affects the cost

Every engagement is a fixed quote based on effort, sent after a short scoping call. You can pay per test, with PTaaS credits or within a subscription, and the work can be timeboxed to fit a set budget.

What moves the quote

01Number of applications, APIs and user roles
02Test type: web, API, mobile, thick client, cloud or network
03How often you want testing: per release, or once or twice a year
04Black-box, grey-box or code-assisted testing
05Compliance reporting needs, such as SOC 2 or PCI DSS
06A set budget, if you want the test timeboxed to fit it

FAQ

Frequently asked questions

How is PTaaS different from a traditional pentest?

A traditional pentest is a single engagement that ends in a report. PTaaS uses the same manual testing but delivers findings on a platform as they are confirmed, integrates with JIRA and makes retesting part of the cycle. See PTaaS vs traditional penetration testing.

How long does a PTaaS test take?

Most tests run days to weeks, depending on scope. We reply in under an hour during US business hours; scope, timeline and a quote follow the scoping call, and findings start appearing as soon as testers confirm them.

Can PTaaS support SOC 2 and PCI DSS?

Yes. The report documents a manual penetration test with scope, method, findings and retest results, which is the evidence auditors typically look for. PCI DSS Requirement 11.4 covers internal, external and segmentation testing. We are not a PCI Approved Scanning Vendor, so ASV scans need a separate provider.

Do findings go into JIRA?

Yes. Findings can be pushed from the PTaaS platform to JIRA as they are confirmed, so they enter your normal engineering workflow. Retest results are recorded on the platform.

Can PTaaS cover more than web apps?

Yes. Credits can be used across web and API, mobile, thick client, cloud and network testing, so you can point testing at whatever changed. See the full list of penetration testing services.
