Who we are

Security testing by the people who work in the code

A security report is only useful once somebody fixes what is in it, and that is usually where the months go.

FusionHit is a software engineering company, so the engineers who find the injection path or the broken access control are the ones who can open the pull request that closes it. Senior engineers across Latin America, working on your hours.

WHAT WE DELIVER

Application security testing services we deliver

Testing the software itself, at the points where applications actually get broken into.

Web application security testing

Manual and automated testing against the OWASP Top 10 and ASVS: injection, broken access control, authentication flaws, and the business-logic abuse a scanner never finds.

API security testing

Authorization tested per endpoint and per object, because an API that checks who you are and not what you may touch is the most common serious finding we report.

Mobile app security testing

Client-side storage, certificate handling, hardcoded secrets and the backend calls the app makes, tested on the platforms your users actually run.

Secure code review

Targeted review of authentication, authorization, cryptography and data handling paths by engineers reading the code, not a tool ranking files by risk score.

Dependency and supply chain scanning

Known vulnerabilities in your libraries and container images identified and triaged by whether the vulnerable path is reachable in your application, rather than handed over as a list of 400 CVEs.

Remediation and re-testing

The fixes implemented or reviewed by our engineers, then re-tested to confirm the finding is actually closed rather than moved.

SCOPE

Where we fit, and where we do not

The other companies on this search are security firms and we are not one. Being clear about that is the fastest way for you to work out whether to talk to us.

What we do

Application security testing inside your release cycle, run by engineers who know the codebase: OWASP-aligned testing, secure code review, dependency triage, and the remediation afterwards. Continuous rather than annual, because a finding raised in the sprint that created it costs a fraction of one found a year later.

What we do not do

We do not issue penetration test attestations, run red team exercises, or sign the letter your auditor wants. Those need a certified offensive-security firm, and telling you otherwise would be selling you a document we cannot produce.

How the two fit together

When you need a formal pentest, we work alongside your assessor: we prepare the environment, answer their questions, and fix what they report. Most of our clients use both, and the findings get cheaper every year because fewer of them survive to the audit.

Why FusionHit

Why US companies choose FusionHit for application security testing

  • Senior engineering talent

    Vetted nearshore engineers with production experience across industries and modern stacks.

  • Real-time collaboration

    Nearshore teams aligned with US time zones for synchronous planning, reviews, and delivery.

  • Flexible engagement

    Scale engineering capacity up or down as your roadmap and priorities evolve.

  • Integrated partnership

    We work as an extension of your engineering and product teams, not as a detached external vendor.

INDUSTRIES

Security testing against the rules your industry is audited on

What counts as an acceptable finding is written by your regulator, not by a severity score.

Fintech

Transaction integrity, authorization boundaries and PCI DSS scope tested where money and access actually meet.

Healthcare

PHI access paths tested against HIPAA requirements, with synthetic records only in every non-production environment.

SaaS

Tenant isolation tested as a first-class case, because cross-tenant access is the finding that ends a SaaS contract.

Logistics

Device, integration and partner-facing endpoints tested where operational systems meet the outside world.

Retail

Checkout, payment handling and customer data paths tested ahead of the season rather than during it.

Manufacturing

The interfaces between plant systems and connected applications tested where IT and OT touch.

HOW WE ENGAGE

Three ways to engage security testing

Staff augmentation

Senior engineers with application security experience added to your team, under your direction, in days rather than months.

Dedicated development teams

A team working only on your product, with security testing part of the definition of done rather than a separate phase.

Full project outsourcing

You hand over the scope and we deliver it under our management, covering testing, triage, remediation and re-test.

OUR PROCESS

How a security testing engagement starts

01

Discovery call

What the application is, what data it holds, and what is driving the timing (30 minutes).

02

Scoping

The surfaces in scope, the standard we test against, and the rules of engagement, agreed in writing.

03

Testing

Automated and manual testing, with anything critical reported the day it is found rather than at the end.

04

Remediation and re-test

Fixes implemented or reviewed, then verified closed against the original finding.

FAQ

FAQs about our application security testing services

01

Is this the same as a penetration test?
No, and the difference matters. We test your application from inside your engineering process, continuously, and fix what we find. A penetration test is a point-in-time engagement by a certified offensive-security firm that produces an attestation for your auditor. If that is what you need, we will say so and work alongside whoever runs it.
02

How much does application security testing cost?
Senior nearshore rates run 30-50% below equivalent US salaries and security consultancy fees. What you pay depends on how much surface is in scope, whether mobile and APIs are included, and whether you want remediation as well as findings. You get a line-item estimate on the first call.
03

What standard do you test against?
The OWASP Top 10 for coverage and OWASP ASVS where a defined assurance level is needed. Both are public, so you can check our work against them rather than against a methodology we invented.
04

Do you fix what you find, or only report it?
Both, and you decide the split. Our engineers can implement the fix, or review and verify a fix your team writes. Either way the finding gets re-tested and closed rather than marked resolved on a spreadsheet.
05

How do you handle critical findings?
Anything critical is reported the day it is found, not held for the final report. You get the finding, the reproduction steps, and our read on the risk, so you can decide whether it needs a hotfix before we finish the rest.
06

Can you test without access to the source code?
Yes, and we would rather have it. Black-box testing finds what an attacker finds; source access finds the things they would find eventually with more time. Most engagements use both.
07

Will testing break our environment?
Not in the way that matters, because we agree the rules of engagement first: what is in scope, what is off limits, rate limits, and who to call. Testing normally runs against staging, and where production is involved it is with an agreed abort condition.
08

How does this work with our compliance requirements?
We test to your framework, whether that is HIPAA, PCI DSS or SOC 2, and produce the evidence your assessor asks for from the work. We do not issue the attestation itself, which has to come from a qualified assessor.
09

Can this run continuously rather than as a one-off?
Yes, and that is where it gets cheap. Testing that runs with your releases catches issues in the sprint that created them, when the developer still has the context and the fix is small. An annual engagement finds a year of accumulated work at once.
10

What about our dependencies and containers?
We scan them and, more importantly, triage them: whether the vulnerable code path is reachable in your application, which usually reduces a list of hundreds of CVEs to a handful that actually matter this week.
11

How fast can this start?
We present matched profiles within days, you interview and approve them, and most engineers onboard in under 2 weeks. A scoped test against a staging environment can often start sooner.
12

How much time zone overlap will we have?
Our engineers work across Latin America on US Central and Eastern time, which gives 6-8 hours of daily overlap. It matters here because a critical finding needs a conversation the same hour, not the next morning.
