What are security testing services?

We test your software, network and cloud setup for weaknesses an attacker could use. You get a ranked list of problems and clear steps to fix them.

What does a security testing services company do?

A security testing services company plans the tests, runs them safely, proves what it finds and helps you fix and retest. At Fulminous Software, engineers review every result by hand.

What is the difference between vulnerability assessment and penetration testing?

A vulnerability assessment finds and ranks known weaknesses, mostly with scans. Penetration testing goes further, with an engineer trying to exploit them to show the real impact.

Do you offer software security testing services?

Yes. Our software security testing services cover code, running apps, APIs and the servers behind them.

Do you provide cyber security testing services?

Yes. Our cyber security testing services look at your apps, network, cloud accounts and any services exposed to the internet.

What do your cyber security penetration testing services include?

Hands-on attack simulation by experienced engineers, with proof, steps to reproduce and a retest after your fixes.

What is the difference between black box, red team and purple team testing?

Black box testing starts with no inside knowledge. A red team runs a longer, quieter attack that also tests your people and detection. In purple teaming, our testers work with your defenders in real time so they learn to stop each step.

Do you offer network security testing services?

Yes. We test firewalls, open ports, VPNs and internal segments from outside and inside your network.

Do you offer security penetration testing services for a single app?

Yes. We can scope the test to one app, one API or one feature, which keeps cost and time down.

Do you provide application security testing services USA clients can rely on?

Yes. Our application security testing services in the USA come with overlapping hours, daily updates and a shared tracker.

Are you one of the best application security testing services providers?

We aim to be. We combine manual testing with tools, show proof for every finding and retest after fixes. Ask for references and judge for yourself.

Do you test web applications?

Yes. Our web application security testing covers login, sessions, forms, access control and common attack types.

Do you test mobile apps?

Yes. Our mobile application security testing covers Android and iOS apps, plus the backend they use.

Do you test cloud environments and IoT devices?

Yes. We review cloud settings for misconfigurations and test connected devices, their apps and the services behind them.

Do you offer AI and LLM security testing?

Yes. We test chatbots and language-model features for prompt injection, data leaks and unsafe actions. We also use AI tools to sort scan results, and an engineer checks every finding.

Do you run phishing simulations and social engineering tests?

Yes, with your written permission. We report results by team and follow up with short awareness guidance.

What are managed application security testing services?

Regular scans, manual tests and retests on a set schedule, with reporting and tracking. It suits teams that release often.

Can I outsource security testing?

Yes. With outsourced security testing, you share the scope and access, and we plan, test and report. You decide what gets fixed first.

Will testing affect my live systems?

We plan test windows with you and prefer staging environments. Where live testing is needed, we use careful methods and agree on limits first.

How long does a test take?

A focused test on one app often takes one to three weeks, from planning to report. Larger programs take longer. We give a timeline after the first call.

How do I choose a software security testing company?

Ask about manual testing, proof for findings, retesting and references. A good partner lets you start small.

How much do security testing services cost?

Projects usually start from $3,000, depending on scope, depth and duration. Hourly engineers cost $20 to $60.

Web Application Security Testing for a USA FinTech Platform

A US fintech company was about to sign a large customer, and the customer asked for a security report. The in-house team had never had an outside test and didn’t know what they would find. After comparing several firms, they chose Fulminous Software, a security testing services company with real fintech experience.

They hired 3 engineers from our team. We ran web application security testing and API security testing, then followed with manual penetration testing. We found a broken access control flaw that let one user read another’s statements, plus a weak password reset flow. Their developers fixed both in a week, and we retested.

The customer received a clean report and signed. The company now books a test before every major release.

Results:

Serious access flaw fixed before any customer saw it
Customer security review passed
Regular testing built into the release plan

Mobile Application Security Testing for a UK Healthcare App

A UK healthcare booking app stored patient details on the phone and wasn’t sure how well they were protected. The team asked us to check before a wider rollout.

A team of 2 engineers ran mobile application security testing on Android and iOS, and reviewed the backend services. We found data saved without encryption and an API that returned more patient detail than the app needed. We shared proof and a short fix list. Their team encrypted the stored data and trimmed the API responses.

The rollout went ahead, and the platform kept us on for every new release.

Results:

Sensitive data now encrypted on the device
API responses limited to what the app needs
Security checks added to each release

Cloud Security Assessment and Phishing Test for a Logistics Company

A logistics company had moved most of its systems to the cloud in a hurry. Nobody had checked the settings since. They also worried about staff clicking on fake delivery emails.

A team of 3 engineers reviewed their cloud accounts and found a storage bucket open to the public and several accounts with far more access than needed. We also ran a phishing simulation with their approval. About a fifth of staff clicked, and their mail filters caught only some of the messages. We shared a fix list and ran short awareness sessions.

The company closed the bucket within a day, tightened access and re-ran the phishing test three months later with better results.

Results:

Public storage exposure closed
Access permissions cut down to what each role needs
Fewer staff clicks on the follow-up phishing test
