We find the weak spots in your systems before someone else does

Penetration testing of web applications, APIs and mobile apps, security audits of websites and online stores, code review. Experience in bug bounty programs of financial institutions and a crypto platform.

5.0 from 4 Google reviews

Most breaches do not start with a sophisticated attack. They start with an outdated plugin, a forgotten test account, an API that returns someone else's data when you change one number in the URL, or an admin panel without a second layer of protection. The owner finds out when customers start calling.

A penetration test is a controlled attack with your permission. We look at the system the way an attacker would, and we tell you what we found, how dangerous it is and how to fix it. No scare words and no 200-page report of raw scanner output.

Where we have worked

Financial and insurance systems, where security requirements are the highest. We have also worked on other projects that we do not list publicly.

Cryptocurrency

altcoins.bg

We found a vulnerability in the platform, reported it responsibly and it was fixed. We publish this with the permission of altcoins.bg; the details remain confidential.

Banking and insurance

Private bug bounty programs

We take part in private bug bounty programs run by financial institutions. Their terms are confidential, so we do not name the companies or describe the findings.

How we work

Responsible disclosure

Every finding goes only to the owner's security team, within the rules of the program, and is never published without permission.

What we test

Web application penetration testing

Manual testing against the OWASP Top 10 and beyond: login and sessions, access rights, injections, file uploads, business logic. We look for what scanners miss.

APIs and mobile apps

REST and GraphQL APIs, mobile apps for iOS and Android: authentication, access to other users' data, information leaks, rate limits.

Website and online store audit

WordPress, WooCommerce and other platforms: outdated plugins, weak passwords, exposed admin panels, wrong permissions, payments and customer personal data.

Code review

We read the application code and look for vulnerabilities at their source. Useful before launching a new product or after a major change.

Servers, cloud and email

Configuration of servers and cloud services, open ports, SSL, DNS, SPF, DKIM and DMARC, so nobody can send email in your name.

Bug bounty and disclosure

We help you set up a vulnerability disclosure program: rules, scope, security.txt and a response process, so you are the first to hear about a problem.

How a test works

Four steps, each with a clear result. You know what is tested, when, and what you will get at the end.

01

Scope and authorization

We agree on which systems, which environment and which timeframe. We sign a contract with written authorization and, if needed, a non-disclosure agreement.

02

Testing

Manual work, supported by tools. We agree on the testing windows so we do not disrupt your customers, and we stop immediately if we find something critical.

03

Report

Every vulnerability with a risk level, proof, steps to reproduce and a specific recommendation. Plus a short plain-language summary for management.

04

Retest

Once your team or we have fixed the issues, we test again and confirm in the report what has been closed.

Price

Custom quote, based on the project and its scope

No two tests are alike. That is why we do not list a price upfront. After a short call we send you a quote with a clear amount (excl. VAT) and timeline, before we start.

What it depends on
  • +How many systems, domains, APIs or applications are in scope
  • +Type of test: no information from the outside, with a user account, or with access to the code
  • +How many roles and user levels the application has
  • +Test or live environment, and the hours when testing is allowed
  • +Timeline, and whether you need a retest after the fixes

The rules we work by

Only with permission

We test only systems for which the owner has given us written permission, and only within the agreed scope.

Confidentiality

What we find stays between us and you. We do not publish vulnerabilities or show reports without your consent.

No unnecessary panic

We rank the problems by real risk. You hear about anything critical right away, by phone, not at the end of the test.

Is your website hosted with us? The basic protection is already part of website maintenance: updates, backups, a protected login and monitoring. A penetration test is the next step once you have an application, payments or a lot of customer data.

Questions about cybersecurity

How much does a penetration test cost?

The price is a custom quote and depends on the scope: number of systems, type of test, roles, environment and timeline. After a short call to define the scope, we send you a quote with a clear price and timeline before we start.

How long does a test take?

A small company website or store takes a few working days. A web application with an API and several user roles usually takes from one to several weeks. The exact timeline is in the quote.

Will our site go down during the test?

It should not. Tests that could put load on the system are run in an agreed window or in a test environment. We do not run denial-of-service attacks unless you explicitly ask for them and we agree on it.

Do you test without the owner's permission?

No. We work only on systems for which we have written permission from the owner, with a clearly defined scope. Bug bounty programs are a public permission with their own rules, and we follow them strictly.

Do you sign a non-disclosure agreement?

Yes. Everything we see during the test stays between us and you. The report goes only to the people you name.

Do you also fix the problems you find?

Yes, if you want us to. We can fix the vulnerabilities ourselves, especially on WordPress and on sites we maintain, or hand the report to your developers and then verify their fixes.

What is bug bounty?

A program in which a company allows outside researchers to look for vulnerabilities in its systems under defined rules and rewards valid reports. We take part in such programs and can help you set up your own.

Работя с Pro Website отскоро и до момента съм изключително доволна. Лично аз не съм компетентна в рекламата в интернет, какви закони трябва да се съблюдават, технически как трябва да се проведе една кампания. Всичко ми обясниха специалистите от Pro Website, пишат ми стъпка по стъпка, какво се изисква от мен, дадоха ми ценни препоръки и насоки, за да е успешно моето представяне в интернет пространството. Надявам се на дългогодишно успешно сътрудничество. Радвам се, че им се доверих.

These guys are very skilled and effective, Especially with integrating AI solutions into a business. I was very impressed with how quickly they could build a customer facing website and solve some of the more difficult problems with A.I and/or code based methods. Definitely at the cutting edge of what’s possible in the world of Web development.
