App and role map
Every role, endpoint, and data store listed, so testing covers the whole app, not just the homepage.
The Problem
Your App Passed the Scanner, but Nobody Checked the Logic
Automated scanners catch missing headers and old libraries. They rarely notice that one customer can open another customer's invoice by changing a number in the URL.
01 · Scanner noise
A free scanner returns a long list of minor findings.
Each finding is reproduced by hand, ranked, and shipped with a fix example.
02 · Role abuse
A viewer account can still call the delete endpoint.
We test every endpoint while logged in as each role you define.
03 · Old libraries
An image library with a known flaw sits in production.
Dependency checks list vulnerable packages and the version that fixes each one.
04 · Cloud storage
A storage bucket lets anyone list its files.
We review cloud and app configuration, including storage, secrets, and security headers.
Your biggest prospect sends a security questionnaire, and one question asks for your latest application security review. You run a free scanner and get a long list of findings, most of them low or duplicated. Meanwhile, the real issues sit elsewhere. A user with the viewer role can still call the delete endpoint. An image library in production has a known flaw. A storage bucket lets anyone list its files. Nobody can say which problems matter, so the questionnaire stays unanswered.
Our application security assessment starts by mapping your app: roles, endpoints, data stores, and third-party services. Then we check five layers, logged in as each role: design, access control, dependencies, configuration, and data handling. Every finding is confirmed by hand and comes with a fix example in your stack. Your developers get a short list of real issues, not a scanner export to sort through.
Five layers, one review
Design, access, dependencies, configuration, and data handling, checked together so gaps between them show up.
Tested as every role
We log in as each user role and try what that role should not be able to do.
Findings confirmed by hand
Every issue is reproduced and explained before it reaches your report, with a fix example.
Our Application Security Assessment Process
From App Intake to Verified Fixes in Five Clear Steps
You approve the scope, roles, and test accounts first, see findings as they're confirmed, and get a retest once your fixes ship.
We learn your stack, your user roles, and the reason for the assessment, such as a customer review or a launch. You get a scope and a fixed price. If a free scanner like ZAP plus a dependency update would cover your case, we'll tell you before we quote.
What's Included
What You Get With a Web Application Security Assessment
A mapped app, five layers assessed, verified findings with fixes, and a retest, so your team knows exactly what to change and when it's done.
Compare Options
DeveloperLook vs Scanner Alone vs Pen Test Only
A scanner is cheap and fast, and a pen test proves what an attacker can exploit. An assessment sits between them: broader than a test, deeper than a scan.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built apps, platforms, and websites for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Product Teams Trust Us With Application Security
An assessment is only useful if developers can act on it. These habits keep findings real, fixes practical, and your release schedule intact.
Developers, not just testers
Our engineers build apps in the same frameworks we assess. Fix examples fit your code, not a generic snippet from a scanner.
No unverified findings
If we can't reproduce an issue, it doesn't go in the report. Your developers spend their time on real problems, not on disproving noise.
Critical issues the same day
When we find something serious, you hear about it the same day. You don't wait for the report to start fixing it.
Staging comes first
We test in staging whenever you have one and touch production only with written approval. Your customers don't notice the assessment.
Plain risk language
Each finding explains what an attacker could actually do, in business terms. Product owners can rank fixes without needing a security background.
Your report to share
You own the report and can share its summary with customers. It describes what we checked honestly, without claiming the app is unbreakable.
Overview

Good fit
SaaS teams facing customer reviews
Your enterprise prospect asks for a recent application security review, and you need a credible report before the deal stalls.
Startups before a public launch
You're about to open signups to everyone, and you want an application vulnerability assessment before real customer data arrives.
Mobile app teams
Your iOS or Android app stores tokens and personal data, and you need a mobile application security assessment against OWASP MASVS.
Teams that inherited a codebase
You took over an app from another agency or developer, and you need an application security analysis before you build on it.
Agencies shipping client apps
Your agency delivers apps to clients who ask for security evidence, and you want assessments delivered under your own brand.
Not a fit
Need a pen test report
A customer or auditor specifically requires a penetration test. Web Application Penetration Testing Services delivers that report.
Design not built yet
Your feature is still a design or a diagram. Threat Modeling Services checks it before code exists, while changes are still cheap.
WordPress or Shopify site
You run a WordPress, Shopify, or other hosted website rather than a custom app. Website Security Audit Services fits that setup better.
Budget under $900
Your budget is under $900. Run a free scanner like ZAP and update your dependencies first, then book an assessment when you can.

A web app security assessment is a structured review of a browser-based app's design, access controls, libraries, settings, and data handling. It looks for weaknesses an attacker could use, then explains how to fix each one. Unlike a pen test, it aims for broad coverage of the app rather than proving how far one attack chain goes.
The main types are automated scanning (DAST), static code analysis (SAST), dependency checks (SCA), configuration reviews, manual assessments, and penetration tests. Each one finds different problems: scanners miss logic flaws, and pen tests often skip dependencies. Our software security assessment combines manual testing with dependency and configuration review, and the top plan adds SAST to your pipeline.
An application security assessment from DeveloperLook starts at $900 for one web app with up to 2 user roles, verified findings, and one retest. Adding APIs, up to 5 roles, and ASVS Level 2 checks costs $2,400. A web and mobile assessment with pipeline scanning is $4,900. Each price is fixed after the free intake call.
Most assessments take 1 to 2 weeks for one web app, and 2 to 3 weeks with APIs or a mobile app. Mapping roles and setting up test accounts usually fills the first few days. The retest happens once your team ships fixes, within 30 days of the report.
Perform an application security gap assessment by comparing your app with OWASP ASVS and marking each requirement met, partly met, or missing. ASVS 5.0 has 3 levels: Level 1 is a baseline, and Level 2 suits most apps with sensitive data. The gaps become your fix list, ranked by risk. We use Level 1 on every plan and Level 2 on larger ones.
You prevent most web application attacks by enforcing access checks on the server, keeping dependencies patched, validating input, and setting secure defaults. The OWASP Top 10:2025 still ranks broken access control first. An application security assessment checklist built from ASVS helps your team apply these habits the same way on every release.
Ensure web application security by adding checks at every stage, from design reviews to dependency scans to assessments before major releases. No single test covers everything, so layers matter. Small teams can start with automated scans in CI and one assessment a year, then add threat modeling for risky features such as payments or roles.
No, an assessment aims for broad coverage, while a pen test tries to prove how far an attacker can get. An assessment checks design, dependencies, and configuration that a pen test may skip, and a pen test goes deeper on exploitation. Many teams run an assessment first, fix the findings, then book a pen test when a customer asks for one.
Yes, the top plan adds one iOS or Android app, checked against the OWASP Mobile Application Security Verification Standard (MASVS). We look at how the app stores tokens and personal data, how it talks to your API, and what it trusts. Mobile and web often share one backend, so we test them together.
After the report, your developers fix the findings while we answer questions, and we retest within 30 days to confirm each fix. The updated report shows what was fixed and what remains open. The top plan adds a second retest, 60 days of fix support, and security scans in your CI pipeline.
