Application Security

Application Security, explained.

Application Security is the practice of finding and fixing weaknesses in web, mobile and API software before they can be exploited, through audits, penetration testing and secure code review. It matters because most breaches don't start with a novel attack; they start with a known weakness nobody checked, such as broken access control, an exposed admin panel or an outdated library.

Esscentra tests applications against recognised standards, the OWASP Top 10 and OWASP ASVS for applications and CIS benchmarks for the infrastructure they run on. We combine automated scanning with manual testing, review source code for design-level flaws that scanners miss, and rank every finding by how exploitable it is and what it would cost the business. Then we help your team fix the issues, or fix them ourselves, and retest to confirm they are closed.

The result is a clear picture of your real exposure and a short list of what to fix first. It fits companies preparing for a customer or investor security review, products that have never been independently tested, and teams that inherited code built without security in mind.

Who it's for

Built for teams like these.

  • 01

    Companies preparing for a customer, investor or compliance security review.

  • 02

    Products that have never had an independent security test.

  • 03

    Teams that inherited a codebase built without security oversight.

  • 04

    Businesses handling payments, health or personal data that need proof of diligence.

How we work

5 steps, from first call to launch.

  1. 01

    Scoping

    We agree which applications, APIs and environments are in scope and how testing will run safely.

  2. 02

    Automated & manual testing

    We scan, then test by hand for access-control, logic and injection flaws.

  3. 03

    Code & configuration review

    We review source code and infrastructure settings for design-level weaknesses.

  4. 04

    Report & fix plan

    We deliver findings ranked by risk, with clear steps to fix each one.

  5. 05

    Fix & retest

    We help fix the issues, or fix them ourselves, and retest to confirm they're closed.

Questions

Questions about application security.

What's the difference between an audit and a penetration test?
An audit reviews your code, design and configuration against standards. A penetration test actively tries to break in the way an attacker would. Most clients get the most value from both together.
Will testing disrupt our live system?
No. We agree the scope, timing and safe methods in advance, and test sensitive areas in a staging environment where possible.
Do you fix the problems you find?
Yes, if you want us to. Many clients have their own team fix the issues using our plan; others have us fix them. Either way, we retest to confirm each fix.
Which standards do you test against?
The OWASP Top 10 and OWASP ASVS for applications and APIs, and CIS benchmarks for servers and cloud configuration.
How much does a security assessment cost?
You get a fixed-price proposal after a free discovery call, based on the number and size of the applications in scope.
