08 · Security Testing

Find the weaknesses before someone else does.

We test your applications, APIs, mobile apps, cloud and internet-facing systems the way an attacker would, within limits agreed in writing, and report what we could actually exploit and how to fix it. Book a single test, or run it as a security service: scheduled testing, continuous checks and a retest every time a fix ships.

When teams call us

You might be here because…

  1. 01An enterprise customer or investor asked for a recent penetration test report.
  2. 02Your auditor expects evidence of security testing for SOC 2, ISO 27001 or PCI DSS.
  3. 03You are about to launch, or just shipped a major release, and want it tested first.
  4. 04Your last test was a scanner report nobody could act on.
  5. 05Security has to be continuous, but a full-time security team isn’t justified yet.

01What we build

Security Testing, in practice.

  • 01

    Web and API penetration testing

    Authentication, authorization and sessions, business-logic flaws, injection, access to other customers’ data and API abuse, tested by hand and aligned with the OWASP Web Security Testing Guide and the OWASP API Security Top 10.

  • 02

    Mobile app testing

    iOS and Android apps and the APIs behind them: data stored on the device, transport security, platform permissions, reverse engineering and tampering, aligned with the OWASP Mobile Application Security Testing Guide.

  • 03

    Cloud configuration review

    AWS, Azure and Google Cloud accounts checked for exposed storage, over-broad IAM roles, missing logging and risky network paths, against the CIS benchmarks.

  • 04

    External network testing

    Your internet-facing hosts and services: what can be reached, what it reveals and what can be exploited from outside.

  • 05

    Vulnerability assessment

    Broad, tool-assisted coverage of known weaknesses with every result checked by a person, so the report holds real issues, not scanner noise.

  • 06

    Security as a service

    Testing that keeps pace with your releases: scheduled tests through the year, continuous checks of dependencies and exposed services, a retest whenever a fix ships, and a written security report every month.

02How we hold the line

The standards that come with it.

Authorized and scoped in writing
Every test starts with a signed authorization and rules of engagement: what is in scope, the testing windows, who to call and what we will not do. Nothing outside the scope is touched.
Exploitability, not scanner output
Findings are confirmed by hand, rated by real impact with CVSS, and come with reproduction steps, evidence and a specific fix.
Retests that close the loop
When you fix something we test it again and update the report, so you can show what was found and what was closed.
Methods we follow
The OWASP testing guides (WSTG, MASTG and the API Security Top 10), PTES and the CIS benchmarks. We say “aligned with”, never “certified by”.

05How engagements run

How engagements run

  • Security as a service

    An ongoing subscription: scheduled tests across the year, continuous checks, retests on every fix and a monthly report, sized to how often you release.

  • Penetration test

    A fixed-scope test of an application, API, mobile app, cloud account or external network, with a report and a retest of fixed findings.

  • Pre-audit test

    A test scoped and timed for an audit or a customer review, with a summary letter you can share and the detailed report kept internal.

Questions

What people ask first.

Security testing becomes part of how you ship instead of a once-a-year event: scheduled tests, continuous checks of dependencies and exposed services, retests whenever fixes land, and a written report every month. It is sized to your release pace, and it can include help fixing what we find.

Not as an independent test. A penetration test should come from people who didn’t build the system, so we offer it for software built by others. On systems we build, security testing is part of our own delivery, and we help you arrange an independent test when you need one.

Testing follows the agreed rules of engagement: time windows, rate limits, and no denial-of-service or destructive actions unless you ask for them in writing. We prefer a staging environment that mirrors production, and we stop and call you if something looks fragile.

Yes. You receive a detailed technical report for your team and, on request, a shorter summary letter of the scope, dates and outcome that you can share.

Some organizations in India, such as government bodies and some regulated financial institutions, must use a CERT-In empanelled auditor for certain audits. NS360 is not empanelled, so tell us if this applies and we’ll say plainly whether we can help or whether you need an empanelled firm.
