The web applications and custom software UAE businesses depend on hold customer data, process payments, and run daily operations, which makes their security a practical concern. Hiring an independent application security freelancer gives you a focused review of how your application handles authentication, access, and input, carried out on systems you own or are authorised to assess.
Application security is a specialised area of cybersecurity concerned with the security of the software itself rather than the surrounding infrastructure. On Mahir, every engagement is scoped and priced up front in AED, with the systems in scope and the level of access agreed in writing before any review or testing begins.
What Is Application Security?
Application security is the practice of reviewing and improving how a web application or piece of custom software protects data and controls access. An application security freelancer examines areas such as authentication, authorization, session handling, and input handling, then documents where the application deviates from recognised secure design practice and where risk concentrates.
The work sits alongside development. A team building a custom web application focuses on features and delivery, while an application security review looks at the same software through the lens of risk: how credentials are verified, how access is enforced between users, how untrusted input is handled, and which dependencies introduce exposure. The two are complementary and often run in parallel during a build.
Reviews range from a design-level assessment to a scoped code review and authorised application testing, depending on what you need and what you can grant access to. Any testing is carried out on systems you own or are explicitly authorised to test, under written permission and agreed rules of engagement, so the engagement stays authorised and predictable throughout.

Define the scope
Agree which application and which areas are in scope, and whether the work is a design review, code review, or authorised testing.
-
Agree access and permissions
Decide what access the reviewer needs, such as a test environment or scoped source code, and put the authorisation in writing.
-
Set rules of engagement
Agree what will and will not be tested and when, so the review stays authorised and avoids disrupting live users.

Clarify deliverables
Confirm you will receive a documented report with prioritised findings and clear recommendations.
-
Plan remediation support
Agree whether the reviewer will support your development team as they work through the findings.
Frequently Asked Questions
What does application security involve?
It involves reviewing how an application handles authentication, authorization, sessions, and input, along with its dependencies and design. The reviewer documents where the application deviates from recognised secure practice and prioritises the findings for your team.
Do you review our source code?
A scoped code review is possible where it is authorised and the access is agreed in writing. It focuses on security-relevant areas of the code rather than a full rewrite, and is carried out on software you own or are permitted to review.
Should a review happen before or after launch?
Both are common. Reviewing before launch helps address issues while changes are inexpensive, while reviewing an existing application is useful after new features or as a periodic check. Many teams do both at different stages.
How are findings prioritized?
Findings are usually grouped by severity and by the effort needed to address them, so your team can focus on the most important items first. The report explains each finding and gives a practical recommendation.
How is remediation supported?
A reviewer can provide prioritised recommendations and work with your development team as they make changes. The pace and outcome depend on your own codebase and resources, so remediation is supported rather than guaranteed.
How is an application security engagement scoped on Mahir?
The application in scope, the type of review, the access required, and the rules of engagement are agreed before work starts. The engagement is priced up front in AED, with payments released against agreed milestones.
