PENETRATION TESTING: THINK LIKE A HACKER, ACT LIKE A DEFENDER


Penetration testing is one of the most effective solutions modern cybersecurity has to offer

They are not just a recommended practice – they are a necessity for any organisation that manages sensitive data, relies on secure digital infrastructure, and wants to maintain the trust of customers and partners.

The objective is clear and focused: a team of security experts simulate targeted attacks against the organisation's systems to identify weaknesses in its defences. This "attacker mindset" approach is highly effective because it not only reveals where vulnerabilities exist, but also how they might be exploited in a real-world scenario. This makes the results of a penetration test much more than just a technical report – they represent a realistic attack scenario that you can proactively prevent.

Penetration testing not only helps identify vulnerabilities, but also verifies and assesses their relevance to your specific IT environment – real, applicable and potentially dangerous to your technologies and processes. Instead of trying to "patch everything" at once, you can prioritise your efforts based on the actual impact of threats on your organisation. This allows you to strike a sustainable balance between security and efficiency.

Penetration tests are valuable not only because they uncover technical vulnerabilities, but also because they reflect your organisation's habits, workflows and response capabilities. They show how employees react to suspicious emails, whether clear incident response procedures are in place, and how long it takes to detect and contain a real threat. While the test is running, you can monitor your internal systems and processes in real time – tracking team behaviour, defensive effectiveness, and the points at which your response mechanisms either activate or stall. This makes the test more than just an assessment – it becomes a hands-on learning experience.

But beyond the how, the when is also important. Many organisations assume that testing every few years is sufficient. Best practice dictates that penetration testing should be conducted at least annually, and after any significant change to your digital ecosystem – such as the introduction of new systems, the expansion of external user access, or significant changes to your security policies. If a breach has already occurred, a penetration test is a critical step in identifying concrete recommendations for strengthening your defences.

Other signs that it is time for a penetration test include unexplained performance drops, unexpected logs in your systems, or just a general feeling that something has changed in the configuration. In a world where hackers never sleep, the "wait and see" approach is rarely successful.

Penetration tests are also a key part of compliance with standards such as ISO 27001, PCI-DSS, GDPR and others. In many cases, they are not just helpful – they are a regulatory requirement.

When the test is complete, organisations do not just get a list of identified issues. They get clear, prioritised recommendations – what needs to change, in what timeframe, with what resources, and how to ensure these issues do not reoccur. This is the foundation for building a sustainable cybersecurity strategy based on real data, not assumptions.

At LIREX, we have been conducting penetration tests for over a decade. For us, this service is not just a compliance checkbox – it is a strategic tool. We work with clients across a wide range of industries – banking, healthcare, manufacturing, e-commerce and the public sector – and we understand how diverse and dynamic the risks can be. That is why we tailor each test to each organisation's specific infrastructure and processes. And the results? They go far beyond a technical report. They deliver embedded expert intelligence – accurate vulnerability analysis, informed risk assessment and a real opportunity to improve your overall security.

Do not wait for hackers to knock on your door. Penetration testing is prevention – think like a hacker, but act as a defender of your entire infrastructure.

Penetration Testing: Мисли като хакер, действай като защитник

Тестовете за пробив (penetration testing) са едно от най-ефективните решения, които съвременната киберсигурност предлага. Това не е просто препоръчителна практика – това е реална необходимост за всяка организация, която управлява чувствителна информация, разчита на сигурна дигитална инфраструктура и иска да опази доверието на своите клиенти и партньори.

Целта на тестовете е ясна и конкретна – екип от експерти по сигурността симулира целенасочени атаки срещу системите на организацията, за да идентифицира слабите места в тяхната защита. Този подход, при който действаме като атакуващия, е изключително ефективен, защото показва не само къде се намират уязвимостите, но и как биха могли да бъдат използвани в реална ситуация. Това превръща резултатите от теста за пробив в нещо много повече от техническа справка – те представляват реалистичен сценарий на възможна атака, която можете да предотвратите навреме.

Тестовете за пробив помагат не само да идентифицирате, но и да верифицирате и оцените уязвимостите, специфични за вашата ИТ среда – реални, приложими и потенциално опасни за вашите технологии и процеси. Вместо да се опитвате да "запушите всички дупки" наведнъж, можете да приоритизирате усилията си според реалното въздействие на заплахите върху организацията. Така се постига устойчив баланс между сигурност и ефективност.

Тестовете за пробив са полезни не само защото разкриват конкретни технически слабости, но и защото служат като огледало на навиците, процесите и реакциите във вашата организация. Те показват как служителите реагират при получаване на съмнителни имейли, дали има ясно дефинирани процедури за действие при инцидент и колко време е необходимо, за да бъде засечена и овладяна реална заплаха. Докато тестовете текат, вие наблюдавате вътрешните си системи и процеси в реално време – следите поведението на екипа, ефективността на защитите и точките, в които механизмите ви за реакция се задействат или блокират. Така тестът се превръща не просто в оценка, а в ценен практически урок.

Но освен как, важен е и въпросът кога. Много организации смятат, че един тест на няколко години е достатъчен. Според добрите практики тестове за пробив трябва да се провеждат поне веднъж годишно и при всяка значима промяна във вашата дигитална екосистема – въвеждане на нови системи, разширяване на достъпа до приложения за външни потребители или съществени промени в политиките за сигурност. Ако вече е имало неочакван пробив в сигурността, тестът е задължителна стъпка към получаване на конкретни препоръки за заздравяване на защитата.

Други признаци, че е време за тест за пробив, са необичайни спадове в производителността, непредвидени логове в системите или дори усещането, че нещо в конфигурацията се е променило. В свят, в който хакерите не спят, принципът "ще изчакаме и ще мине" рядко води до успех.

Тестовете за пробив са и част от задължителните процеси по съответствие със стандарти като ISO 27001, PCI-DSS, GDPR и други. Тоест, те не са само полезни – в много случаи са и регулаторно изискване.

След проведените тестове организациите не просто получават списък с регистрираните проблеми. Те получават ясни, приоритетни препоръки – какво да се промени, в какъв срок, с какъв ресурс и как да се гарантира, че проблемите няма да се повторят. Това е основата за изграждане на устойчива стратегия за киберзащита, базирана на реални данни, а не на предположения.

В LIREX провеждаме тестове за пробив повече от десетилетие. За нас тази услуга не е просто "чеклист" от изисквания – тя е стратегически инструмент. Работим с клиенти от различни индустрии – банки, здравни институции, производствени компании, електронна търговия и публичния сектор – и знаем колко различни и динамични могат да бъдат рисковете. Именно затова адаптираме всеки тест към конкретната инфраструктура и процеси на организацията. А резултатите – те са далеч отвъд технически доклад и препоръки. Те са вградена експертна интелигентност – точен анализ на уязвимостите, обоснована оценка на риска и възможност за реално въздействие върху сигурността.

Не чакайте хакерите да почукат на вратата ви. Тестовете за пробив са превенция – мислете като хакер, но действайте като защитник на цялостната си инфраструктура.
