Why Penetration Testing Matters Now

Romania’s digital economy is expanding fast internet penetration is high and EU cyber rules NIS2, GDPR are biting. As a result, companies must test their defenses proactively. Penetration testing pen testing simulates real cyber attacks under controlled conditions to expose exploitable flaws.

In NIST’s terms, a pen test mimics real world attacks using real tools and techniques to find ways around security features. In practice, pentesters scour networks, applications, and devices for critical issues e.g. OWASP Top 10 web flaws before criminals do.

Insider threats and ransomware are surging: IBM reports 83% of organizations saw an insider attack in 2024, and a global ransomware wave has hit Romanian hospitals and utilities recently. Meanwhile, Romania’s new NIS2 regulations targeted at energy, finance, healthcare, etc. will require periodic pentests and risk assessments.

According to Mordor Intelligence, NIS2 implementation is a key driver +2.3% CAGR impact of Romania’s cybersecurity market. In short, whether for compliance NIS2, ISO 27001, GDPR or simply to find hidden holes in your security, pentesting is a must have in 2025.

What Is Penetration Testing?

“Cybersecurity analyst at multiple holographic screens showing an attack-simulation workflow — reconnaissance, exploitation, remediation — symbolizing the penetration testing process.”

Penetration testing or pen testing is a structured security audit by ethical hackers. It goes beyond scanning tools. As NIST explains, pen tests involve evaluators mimicing real world attacks on systems, networks or apps to see if they can break in. The goal is to uncover vulnerabilities, misconfigurations, code flaws, missing patches, etc. and exploit them to prove real risk. Typical pentest scopes include:

The outcome is a technical report with prioritized findings, proof of concept exploits, and remediation guidance. These reports help businesses fix issues before real attackers exploit them. For example, a vulnerability scan might flag an open port, but a pentester can chain that to full system takeover, a key difference from a simple vulnerability assessment.

Pen testing differs from a basic security audit: it’s manual, adversarial, and goal oriented. It shows how an attacker could actually penetrate, not just where known flaws exist. As one penetration tester notes, this attacker’s eye view enhances resilience and safeguards critical assets.

Romania’s Cybersecurity Context 2025

“Stylized map of Romania connected by teal data lines and overlaid with NIS2, GDPR, and ISO 27001 icons, symbolizing the country’s cybersecurity growth and compliance landscape.”

Romania’s cybersecurity market is on a growth trajectory. Analysts forecast it will grow from $194M in 2025 to $326M by 2030 10.9% CAGR. Key drivers include: accelerated cloud adoption, government digitalization grants, and compliance mandates.

The EU’s NIS2 Directive is particularly impactful utilities, banks, healthcare and large tech firms must now register, assess risks, and undergo regular security testing. Major urban centers like Bucharest and Cluj Napoca house Romania’s tech sector, and demand for pentesting services is highest there.

Compliance requirements further spur pentesting. Many frameworks ISO 27001, PCI DSS 11.3, HIPAA, SOC2, etc. explicitly require periodic pentests or equivalent threat assessments. For example, under ISO 27001 a company must test technical controls; penetration testing is a proven way to do that. Likewise, banks often demand pentest reports to satisfy regulators. Even cyber insurance policies now often require a fresh pentest as proof of due diligence.

In short, Romanian organizations face tougher cyber norms than ever. Regular penetration testing complemented by vulnerability scans helps ensure you meet GDPR/NIS2 standards and reinforce your security before regulators and hackers strike.

How to Choose a Romanian Pentesting Partner

“Business executive analyzing holographic pentesting vendor profiles with OSCP, CREST, and ISO 27001 badges over a digital map of Romania — representing the process of choosing a trusted security testing partner.”

Choosing the right firm depends on your needs and budget. Here are key steps:

  1. Define Scope Clearly: Decide what to test web apps, mobile apps, internal network, cloud infrastructure, IoT, social engineering, etc. Set goals e.g. compliance vs overall risk. A precise scope yields accurate quotes and avoids surprises.
  2. Check Experience & Certifications: Verify testers’ credentials e.g. OSCP, OSCE, CEH, CREST, CISSP and company accreditations ISO 27001, CREST, PASSI, PCI ASV. Experienced pentesters often have bug bounty or corporate security backgrounds. For example, Romania’s top firms emphasize OSCP/CREST certifications and former red teamers.
  3. Ask About Methodology: Good vendors follow standards like OWASP, NIST SP 800 115 or PTES. They should explain their testing process recon, exploitation, reporting, retesting. Ensure they cover black box, gray box or white box as appropriate for your risk appetite. Black box means no prior info; white box means source code access; many tests are gray box partial knowledge.
  4. Review Sample Reports: Demand a redacted report example. Look for clear risk ratings, remediation advice, and proof of exploit. Top testers provide developer friendly reports with screenshots, code snippets and prioritized fixes.
  5. Compare Models & Tools: Decide between a one off audit or ongoing PTaaS continuous testing. PTaaS penetration testing as a service offers subscription or credit models for regular scans and dev integrations. Check if the provider uses automated scanners for breadth plus manual efforts for depth. Some integrate findings into issue trackers Jira, GitHub for seamless workflow.
  6. Evaluate Cost and Coverage: Get multiple quotes. Understand pricing models: per day, fixed fee, or subscription. For reference, small web app tests often run $3K- $10K 3- 10 tester days, while larger projects scale up. Beware of very low bids they may be shallow. Ensure the quote includes retesting support: best firms like DeepStrike offer unlimited retests within the engagement period.
  7. Verify Domain Expertise: If you’re in finance, healthcare or another regulated field, choose a firm familiar with those compliance needs. Many Romanian pentesters tailor reports for ISO 27001, PCI DSS, GDPR or NIS2 checklists.
  8. Check References and Reviews: Look for client testimonials some companies like CTD list client CEOs. You can also see third party ratings Clutch, DesignRush for example, Black Bullet is noted as a Top Tier provider with 5★ reviews.
  9. Plan for Remediation: Good vendors don’t just hand you a report they help remediate. Ask if they provide consulting or retesting. A strong partner will guide your developers through fixes.

By following these steps see also our penetration testing RFP writing guide for more, you’ll pick a provider that fits your threat profile and gives actionable results. Remember: depth and clarity of findings are more valuable than the lowest price.
