Penetration Testing and Red Teaming

Test your company’s security before hackers do. Penetration testing of web applications, on-premises infrastructure, cloud, phishing campaigns, and Red Teaming. We are SYSNETSHIELD, your partner in cybersecurity.

Not sure where to start?

Start with a free vulnerability scan. It will show you what is visible from the internet–open ports, outdated services, and HTTPS configuration errors. Free and without obligation.

How our services connect

You don’t have to start with the most demanding service. For most clients, this sequence makes sense–each step builds on the previous one:

Find out what is visible from the outside–start with a free scan; it shows open ports, outdated software, and SSL errors, for free and within 48 hours

Map out where you stand–a security audit evaluates processes, policies, and regulatory compliance, and determines which areas have priority

Verify that measures are working–a penetration test checks if gaps are actually exploitable; in parallel, it makes sense to test the human factor with a phishing simulation

Test the entire organizationred teaming tests technology, processes, and people all at once and measures how quickly your team detects and stops the attack

Team Certifications

Both CRTO and CPTS are fully practical certifications–the exam consists of a multi-day attack in a laboratory environment and the preparation of a report, not a multiple-choice test.

What sets us apart

Specialized team, not subcontractors

We are not a consultancy firm that resells work. Every project is led directly by members of our team with full responsibility for the result.

Manual work, not just automated tools

Automated scanners detect known vulnerabilities. Logic errors, business-logic flaws, and exploit chains can only be uncovered by an experienced tester who thinks like an attacker.

Actionable outputs

The report is not an academic exercise. It is written so that your dev or ops team can start remediation immediately–with specific steps and links to resources.

Tailored scenarios, not templates

We build every project according to your environment, your risks, and your goals. We do not use off-the-shelf methodologies or generic templates.

Discretion and confidentiality

We sign an NDA before every project. All information and results remain exclusively between us and you.

Compliance with international standards

The methodology is based on OWASP, PTES, and NIST and is in compliance with NIS2 and the Cybersecurity Act–meaning it is recognized by regulators and auditors.
