What Is Pentestica? A Manual Penetration Testing Company
Pentestica is one of the best companies specializing in penetration testing working with clients globally. Our certified testers (OSCP, OSCE, CISSP) manually test web applications, APIs, mobile apps, cloud and network infrastructure, and smart contracts, and run red team and TLPT engagements. Testing is aligned with OWASP, PTES and NIST SP 800-115. Every project ends with an executive summary for management and a technical report for IT, and a retest is available after you fix the findings.
Clients come to us for evidence rather than a list of possible issues: proof that a vulnerability can be exploited, what it exposes, and how to fix it. We work remotely as your external offensive security team, next to your developers and IT staff. See the full list of our penetration testing services.
Experience & Expertise
Our team consists of certified pentesters with over 10 years of experience in cybersecurity and penetration testing. We have successfully completed hundreds of projects, ranging from small businesses to large enterprises and the financial sector.
Comprehensive Services
We focus on offensive security testing: manual penetration tests of applications, APIs, networks and cloud, plus Red Teaming and TLPT. We scope tests for regulatory requirements such as NIS2, DORA, GDPR, HIPAA and PCI DSS.
Innovative Methodology
Tools handle reconnaissance and coverage; people do the exploitation. Our testers chain small weaknesses into real attack paths, test business logic that scanners cannot read, and verify every finding by hand before it goes into your pentest report.
PROVEN PENTESTING METHODOLOGY
What Does a Penetration Testing Company Do?
A penetration testing company attacks your systems with your permission and shows which weaknesses a real attacker could use, and how to fix them. At Pentestica that happens in four stages: we agree a written scope and rules of engagement, certified testers exploit vulnerabilities by hand, we report every verified finding with evidence and remediation steps, and a retest is available once you have patched. Our workflow is aligned with OWASP WSTG, PTES and NIST SP 800-115.
Scoping & Reconnaissance
Every successful penetration test begins with a clear scope. We work with you to define the rules of engagement and identify key assets. Our team performs deep reconnaissance (OSINT) to map your attack surface before the active pentesting phase begins.
Exploitation & Analysis
This is where our certified pentesters simulate real-world attacks. We combine manual exploitation techniques with advanced automated tools to uncover critical vulnerabilities. We verify every finding to ensure your pentest results are accurate and reliable.
Reporting & Remediation
You receive a comprehensive report prioritizing risks by business impact as well as technical severity. We guide you through the remediation process and offer re-testing to confirm that all security gaps identified during the penetration testing are fully closed.
PENTESTING EXPERTS AT PENTESTICA
Specialized Penetration Testing Services
Each service below is a manual test scoped to one environment, with its own methodology and test cases. Pick the one that matches what you need to protect, or compare them all on our penetration testing services page.
Web App & API Penetration Testing
Web applications are the most common attack vector. Our pentesters analyze your web apps and APIs (REST/SOAP) to find OWASP Top 10 vulnerabilities like SQL Injection or XSS. Secure your customer data with a rigorous application pentest.
See web application penetration testing and API penetration testing.
Regulatory Compliance Pentesting
Do you need a penetration test for NIS2, DORA, GDPR, HIPAA or PCI DSS? We scope the test to the requirement and deliver a report your auditor can use as evidence. We don’t certify compliance.
Infrastructure & Cloud Pentesting
We test your internal networks, Wi-Fi, and cloud environments (AWS and Azure). This penetration test identifies misconfigurations and weak points in your servers and firewalls, so you can fix them before an attacker finds them.
Smart Contract Penetration Testing
Securing Web3 requires a different mindset. Our specialized pentesters audit smart contracts and blockchain logic to prevent costly exploits. Trust our expertise in decentralized finance (DeFi) security testing.
AI & LLM Penetration Testing
A manual AI penetration test shows whether your LLM apps, AI agents and RAG pipelines can be made to leak data, abuse tools or take actions they shouldn’t. Test cases are aligned with the OWASP Top 10 for LLM Applications.
Penetration Testing as a Service (PTaaS)
Shipping often? Get recurring manual penetration tests and testing after releases instead of one annual check. Scope and cadence are agreed in writing, and a retest is available after fixes.
Social Engineering Testing
Your people are part of the attack surface. Our pentesters run authorized phishing, vishing and pretexting simulations under written rules of engagement to show how your team and verification steps handle deception.
Cybersecurity Consulting & vCISO
Turn test findings into a security plan. Senior pentesters deliver vCISO support, risk assessments, tabletop exercises and threat modeling based on what they see in real penetration tests.
TLPT (Threat-Led Penetration Testing)
Advanced simulation for critical sectors. Unlike a standard pentest, TLPT is driven by threat intelligence. We simulate specific adversary tactics (TTPs) to test your defense capabilities under realistic conditions.
Red Teaming Operations
The ultimate reality check. While a standard penetration test finds vulnerabilities, Red Teaming tests your reaction. We launch an objective-driven attack simulation across your perimeter, cloud and internal network to see if your team can detect and stop our pentesters in time.
CHOOSING A PENTEST PARTNER
How Do You Choose a Penetration Testing Company?
Choose a penetration testing company by checking how it proves its work, not by price alone. A low or high quote does not tell you whether you are buying a manual test or a scan, so ask every provider on your shortlist for these six things:
- Manual exploitation evidence: findings backed by screenshots, requests and reproduction steps, not raw scanner output.
- Qualified testers: ask which certifications the testers on your project hold, such as OSCP, OSCE or CISSP, and how many years of offensive work they have.
- A fixed written scope and tester-days: targets, test type and effort agreed in writing before any testing starts.
- A sample report: a redacted example showing the executive summary and the technical findings you will receive (see our sample report).
- Retest available after fixes: a second round of testing that confirms your fixes closed each issue.
- Regulatory mapping: findings linked to the requirement you must meet, for example PCI DSS 11.4, DORA or NIS2.

Advanced Tech Protection
Mobile apps on iOS and Android, cloud environments on AWS and Azure, and smart contracts: our penetration tests cover the technology your product runs on, so it can grow without critical vulnerabilities.
Attack Path Discovery
We look for the routes an attacker would take through your systems. Our manual pentesting methodology finds and documents exploitable weaknesses before they impact your business operations.
Support & Knowledge Transfer
After every pentest, we walk your developers and IT staff through the findings: how each attack worked, why the fix closes it, and how to stop the same class of bug from coming back.
CYBERSECURITY TRAINING & AWARENESS
Beyond the Pentest: Building Your Internal Defense
Security depends on people as much as on technology. Our deep expertise in penetration testing allows us to see the digital world through an attacker’s eyes.
Every pentest ends with a knowledge transfer: we show your team the attack paths we used and how to close them. By understanding the mindset of a professional pentester, your employees become the first line of defense against sophisticated cyber threats.
Our comprehensive security training includes:
Practical Pentesting Workshops Learn how pentesters break into systems. We show your IT staff the tools and techniques used in a real penetration test, helping them identify risks proactively.
Phishing Awareness Training Technology can’t stop every click. We train your staff to recognize manipulation and suspicious activities before they lead to a breach.
Secure Coding for Developers Fix bugs before they go live. We teach your developers how to write secure code, reducing the number of vulnerabilities found in future pentests.
A trained team spots phishing attempts and insecure code earlier, which means fewer findings in your next pentest and fewer incidents between tests.
Frequently Asked Questions about Pentesting
Everything you need to know about our penetration testing process, methodology, and results.
What is penetration testing and why does my company need it?
Penetration testing (or ethical hacking) is a simulated cyberattack against your computer system to check for exploitable vulnerabilities. Unlike a real attack, our certified pentesters do this safely to identify weak points. You need it to protect sensitive data, comply with regulations (like NIS2 or DORA), and prevent costly data breaches.
Will a penetration test disrupt my business operations?
Generally, no. We design our pentesting procedures to be non-intrusive. We monitor system stability in real time. Denial-of-service and load testing are never in scope. We agree a testing window with you, and if anything degrades, testing stops and we call your emergency contact.
What is the difference between automated scanning and manual pentesting?
Automated scanners find known, surface-level bugs. Manual pentesting involves a human expert (pentester) who uses logic and creativity to find complex vulnerabilities that machines miss (e.g., business logic errors). At Pentestica, we combine both: advanced automation for speed and rigorous manual testing for depth. Read the full comparison in penetration testing vs vulnerability scanning.
How long does a standard penetration test take?
The duration depends on the scope (e.g., size of the infrastructure, number of API endpoints). A typical penetration testcan take anywhere from 1 to 3 weeks. After the testing phase, we need a few additional days to analyze the data and prepare the comprehensive report.
Can your pentesters help with NIS2, DORA, and GDPR compliance?
Absolutely. Our penetration testing services are aligned with major regulatory standards. For financial institutions and critical infrastructure entities under DORA, NIS2, and GDPR, the report gives evidence for their own risk assessment and audit; we don’t certify compliance. Our reports serve as proof of due diligence for auditors.
What do I receive after the pentest is finished?
You receive a detailed final report containing two parts: an Executive Summary for management (explaining business risks) and a Technical Report for your IT team. This includes a list of all vulnerabilities, evidence of exploitation, and step-by-step remediation guidelines to fix the issues found during the pentest.
What is the difference between Black Box, White Box, and Grey Box testing?
These terms define how much information our pentesters have before starting:
Black Box: We have zero prior knowledge (simulating an external hacker).
White Box: We have full access (source code, architecture) for a thorough audit.
Grey Box: A mix of both (e.g., user credentials provided). We help you choose the best approach for your specific penetration test.
How often should I schedule a penetration test?
Industry best practices and regulations (like PCI DSS) recommend conducting a penetration test at least once a year. However, you should also perform a pentest whenever you make significant changes to your infrastructure, release major code updates, or migrate to a new cloud environment.
Do you offer re-testing after we fix the vulnerabilities?
Yes, we offer re-testing after fixes. Once your team applies the fixes based on our report, our pentesters verify that the patches are effective and that no new issues were introduced. We ensure the security hole is truly closed.
How much does a professional penetration test cost?
The cost is calculated based on the complexity of the project and the number of tester-days required by our pentesters. While every project is unique, here are our typical price ranges:
Standard Web Application / API Pentest: Usually ranges from $2,500 to $5,500. This covers standard business logic and OWASP Top 10 vulnerabilities.
Mobile Application Pentest: from $3,500 for a mobile app (iOS or Android); testing both platforms is quoted in tester-days. See mobile app penetration testing.
Complex Infrastructure / Cloud Audit: Projects involving extensive networks or cloud environments (AWS/Azure) usually range between $5,000 and $12,000+.
Red Teaming: These are advanced, multi-week operations starting from $15,000. A full DORA TLPT is scoped and quoted individually.
We offer a flexible model: you pay for the expertise and time required to thoroughly secure your assets, with no hidden fees. See the full penetration testing cost guide for a breakdown by test type, or contact us for a precise quote. For market context, see our penetration testing cost benchmarks.
