Rigorous Application Security Testing Services

Security testing asks a different question from the rest of QA. Functional testing checks that the software does what it should. Security testing checks what it does when someone deliberately tries to make it behave otherwise: manipulating inputs, reusing tokens, requesting records belonging to another account, or reaching an endpoint the interface never offers.

Benefits of Security Testing

Explore the benefits AgileTech Vietnam delivers for every application security testing services engagement.

Access Control Flaws Found Before They Are Exploited

The most damaging application vulnerabilities are rarely exotic. They are ordinary endpoints that fail to check whether the caller is entitled to the record requested. A scanner cannot judge this, because both requests are technically valid, and only a tester who understands your permission model can tell that one of them should have been refused.

Findings Ranked by Exploitability, Not by Tool Severity

Automated tools report a large volume of issues, and a substantial share are either not exploitable in your configuration or lead nowhere. We verify findings manually and rank them by what an attacker could actually reach, so remediation effort is spent where the risk is real rather than distributed evenly across a long list.

Evidence for Customers, Partners, and Procurement

Enterprise buyers and partners increasingly ask what security testing has been performed before they will integrate or sign. A documented assessment with findings, remediation, and retest results answers that question with evidence rather than assurance, which shortens security review during procurement.

Our Security Testing Process

Six phases from agreed scope and authorisation through to verified remediation, with manual verification behind every reported finding.

Scoping and Written Authorisation

We agree exactly which applications, environments, and endpoints are in scope, which techniques are permitted, and when testing takes place. Written authorisation is obtained before any activity begins. Security testing without explicit permission is not a service, and any partner willing to skip this step is a risk in itself.

Reconnaissance and Threat Modelling

We map the application surface: entry points, roles, trust boundaries, third party integrations, and where sensitive data is held and moves. This determines what an attacker would target first and focuses the assessment on the paths that would matter, rather than testing every input with equal weight.

Automated Scanning

We run OWASP ZAP, Burp Suite, and SonarQube for static analysis of code where it is available. Scanning gives breadth quickly and catches known patterns. Treated as the whole assessment it produces both false alarms and false comfort, so it is where the work starts rather than where it finishes.

Manual Testing and Verification

Engineers manually test authentication, session management, authorisation between roles and between accounts, input handling, and business logic abuse. Every automated finding is verified by hand before it is reported. Logic flaws, where a legitimate sequence of valid requests produces an outcome that should not be permitted, are found only this way.

Risk Assessment and Reporting

Each confirmed finding is documented with reproduction steps, evidence, the affected component, the realistic impact, and a specific remediation recommendation. Risk ratings reflect exploitability in your context. We also list what was tested and found sound, because that is part of an honest picture.

Remediation Support and Retest

We are available to your developers while fixes are made, then retest each finding to confirm it is resolved and that the fix has not introduced a new weakness. A vulnerability report without a retest records that a problem existed, not that it was solved.

Every Finding Verified by Hand

Scanner output is a starting point, not a report. We confirm each issue manually before it reaches you, because an unverified list wastes developer time on findings that turn out not to be exploitable.

We Test Business Logic, Not Only Known Patterns

The flaws that cause real damage are often sequences of entirely valid requests that produce an outcome nobody intended. Detecting those requires understanding what your application is for, which no tool does.

Clear About What This Service Is and Is Not

This is application security testing carried out by engineers. Where you need an accredited penetration test or a formal compliance audit, we say so and help you scope it rather than presenting our work as something it is not.

Our Own Practices Are Certified

We operate a security management system supported by ISO 27001:2013 and a quality management system verified by ISO 9001:2015. That governs how we handle the access and the findings your engagement generates.

Reports Written for Developers

Each finding carries reproduction steps, evidence, and a specific recommendation for the component concerned. A report that names a vulnerability class without showing how it manifests in your code cannot be acted on directly.

Findings Handled Confidentially

A vulnerability report is a map of how to attack your system. Ours are transmitted and stored under the controls of our ISO 27001 supported practices, and we agree disclosure and retention terms with you in writing before testing begins.

Who can Benefit from AgileTech's Security Testing Services?

Applications Holding Personal or Financial Data

Any system storing customer records, payment details, health information, or identity documents carries consequences beyond the technical when it is breached, including regulatory exposure and a loss of trust that outlasts the incident.

Products Entering Enterprise or Regulated Markets

Larger customers run security review before they integrate, and increasingly ask what testing has been performed and what it found. An unanswered questionnaire can stall a deal for months.

Teams Shipping Quickly Without Dedicated Security Review

Fast delivery is not inherently insecure, but it does mean access control changes accumulate without anyone examining them as a whole. Permission logic that made sense feature by feature can contain gaps that only appear when the model is reviewed together.

Best Practices for Choosing your Security Testing Partner

Six practical steps to evaluate and select the right partner for your project.

Ask what proportion of the work is manual

If the assessment is essentially a scan with a cover page, you are paying for tooling you could run yourself. Ask specifically how authorisation between accounts and business logic abuse will be tested, since neither is found by scanning.

Check they distinguish assessment from accredited penetration testing

These are different products with different credentials behind them. A partner who blurs the line may leave you presenting the wrong evidence to a regulator or a customer, which is discovered at the worst moment.

Require written authorisation before any testing

Scope, permitted techniques, and timing should be agreed in writing. A partner willing to begin without this is demonstrating exactly the disregard for process you are hiring them to detect.

Confirm a retest is included

A report proves a vulnerability existed. Only a retest proves it is gone. Establish whether retesting is included and whether it covers fixes that introduce new problems.

Establish how findings will be handled and stored

A vulnerability report is sensitive material. Agree transmission, storage, retention, and deletion terms before the engagement, and ask what security certification governs the partner own practices.

Look for what they tested and found sound

A report listing only failures gives no sense of coverage. Knowing which areas were examined and held up is necessary to understand what the assessment actually covered.

Flexible Engagement Models

Choose the engagement model that fits your project size, budget, and timeline. All models include dedicated communication channels and transparent progress tracking.

Frequently Asked Questions

What is the difference between security testing and the other types of testing you provide?

Functional testing asks whether the software does what was specified. Performance testing asks whether it holds up under load. Security testing asks whether it can be made to do something it should not, by someone deliberately trying. Automation testing is a delivery mechanism for repeatable checks rather than a separate type. Security testing differs from the others in assuming an adversary rather than a user, which is why it finds problems the other three are not designed to look for.

Is this the same as a penetration test?

Not exactly, and the distinction matters. We perform application security testing: authentication, authorisation, session handling, input validation, data protection, and business logic abuse, combining automated scanning with manual verification. A formal penetration test delivered by an accredited firm under a recognised scheme is a different product with different credentials behind it. If your requirement is an accredited attestation for a regulator or a specific customer, we will tell you so and help you scope it rather than presenting our assessment as one.

Can you certify us as compliant with PCI DSS, HIPAA, or similar standards?

No. We are not a qualified security assessor, a certification body, or a compliance auditor for those schemes, and any firm telling you otherwise without the relevant accreditation should be treated with caution. What we can do is test your application against the technical controls those standards expect, so that you enter a formal audit having already found and fixed the issues an auditor would raise.

Do you need access to our source code?

It is useful but not required. Black box testing works against the running application and reflects an external attacker perspective. Access to code allows static analysis with SonarQube and makes some classes of issue considerably easier to confirm and locate. We will recommend which approach suits your risk and budget, and both are legitimate choices.

What tools do you use for security testing?

OWASP ZAP and Burp Suite for dynamic testing, and SonarQube for static analysis where source access is available. These provide breadth. The manual testing that follows provides the depth, and every automated finding is verified by hand before it reaches your report.

Will you fix the vulnerabilities you find?

The assessment identifies, evidences, and prioritises them, and we support your developers while they remediate. Implementing the fixes is separate work that your team may perform or that we can quote for through our development services. Keeping assessment and remediation distinct means the findings are not shaped by an interest in selling the fix.

How often should application security testing be repeated?

That depends on how quickly the application changes and what it holds. Systems handling sensitive data and shipping frequently benefit from regular assessment, since each release can alter the access control surface. We would rather discuss your release cadence and risk than publish an interval that suits some products and misleads others.

How do you handle the vulnerability report itself?

It is treated as sensitive material, because it is effectively a map of how to attack your system. Transmission, storage, retention, and deletion are agreed with you in writing before testing begins and handled under our ISO 27001:2013 supported security management practices.

Is AgileTech Vietnam ISO certified?

Yes. Our security management practices are supported by ISO 27001:2013 and our quality management practices are verified by ISO 9001:2015. These certify how we operate as a company, including how we handle client access and findings. They are not penetration testing accreditations, and we do not present them as such.
