Global Penetration Testing Services for Stronger Cyber Defense

ZealsTECH delivers expert penetration testing services through manual analysis and automated penetration testing to uncover exploitable weaknesses across applications networks infrastructure APIs mobile systems endpoints and cloud environments before attackers cause damage.

Hidden Vulnerabilities Put Your Business Data At Risk

Most companies deploy apps and infrastructure without real security and penetration testing coverage Attackers exploit gaps in web apps APIs and networks before you detect them Lack of standard penetration test and weak penetration testing methodology leaves blind spots Manual pen testing is slow while automated penetration testing alone misses logic flaws Without proper penetration testing steps and penetration testing framework businesses face data loss compliance penalties and brand damage If you never run an external pen test or internal penetration testing hackers will find what your tools cannot see and your cyber security pen testing remains incomplete.

We Find Exploitable Weaknesses Before Attackers Do

ZealsTECH provides complete penetration testing services as a certified penetration testing service provider We follow proven penetration testing methodology and penetration testing framework to test web app pentesting mobile application penetration testing and infrastructure penetration testing Our team uses best network penetration testing tools and tools used in penetration testing for accuracy We perform external penetration testing internal penetration testing and application programming interface security testing Every engagement ends with detailed penetration testing report showing risks impact and fixes As top cybersecurity firms for penetration testing we deliver pentest as a service without overhead and ensure penetration testing security across all systems.

Network (Internal & External) Testing

We conduct a thorough examination of your network to uncover and safely exploit a broad spectrum of security vulnerabilities. This process allows us to determine whether critical assets, such as sensitive data, could be compromised. We then classify the risks these vulnerabilities pose to your overall cybersecurity posture, prioritize the issues requiring immediate attention, and provide actionable recommendations to effectively mitigate the identified threats.

We help prevent modern network security risks, including those related to remote work, cloud migration, IoT devices, and BYOD policy.

Endpoints: PCs, laptops, mobile devices.
Security solutions: firewalls, VPN, IAM, DLP systems
Email services.
Networking devices and network management tools.  

Application Testing

Applications are essential to business growth and daily operations, but they are also a prime target for cyberattacks. Our ethical hacking services include comprehensive website and application penetration testing to uncover vulnerabilities such as SQL injection, cross-site scripting (XSS), flaws in application logic, and weaknesses in session management.

By replicating real-world attack methods, we identify security gaps that could be exploited by malicious actors and provide clear recommendations to strengthen your defenses.

Common Security Vulnerabilities

Our ethical hacking and penetration testing services are designed to proactively uncover and safely exploit security weaknesses within your systems. By identifying vulnerabilities early and providing clear, actionable guidance for remediation, we help your organization gain a deeper understanding of its security posture and significantly lower overall cyber risk.

Common Vulnerabilities We Test For

Insecure Configurations

Misconfigured systems and services often provide attackers with an easy entry point. Our testing identifies:

Open or unused ports left exposed to the internet
Weak or default password credentials
Excessive or unsafe user privileges (admin rights granted unnecessarily)
Misconfigured firewalls, routers, or access control lists (ACLs)
Hidden configuration flaws that can be exploited to bypass security

Flaws In Encryption

Weak encryption makes it easier for attackers to steal or tamper with sensitive information. We assess:

Outdated or deprecated encryption algorithms (e.g., MD5, SHA-1, SSLv2/v3)
Poor implementation of TLS/SSL certificates
Weak key management practices
Improper storage or transmission of sensitive data in plaintext
Risks of data interception, tampering, and eavesdropping

Programming Weaknesses

Applications often contain coding flaws that expose organizations to serious risks. We examine for:

Code injection vulnerabilities (e.g., SQL injection, LDAP injection, command injection)
Buffer overflows and memory handling errors
Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF)
Insecure error handling or debugging messages that leak system details
Use of outdated or unpatched software libraries and components

Session Management Flaws

Weak session management leaves users and systems vulnerable to identity theft and privilege escalation. We test:

Predictable or insecure session IDs
Weak handling of authentication tokens and cookies
Session fixation and session hijacking risks
Insufficient timeout policies for idle sessions
Flaws in multi-factor authentication (MFA) enforcement

Additional Vulnerabilities

Beyond the core categories above, our penetration testing also uncovers:

Reporting You Can Rely On

We don’t just hand over a raw list of vulnerabilities and leave you to figure out the rest. Our post-assessment reporting is designed to give you clarity, context, and actionable next steps.

With every penetration test, you’ll receive:

Our reports bridge the gap between technical findings and business decision-making, ensuring you have both the visibility and the roadmap to strengthen your security posture.

Our penetration testing process

ZealsTECH’s security penetration testing services are based on a systematic approach to vulnerability identification and reporting. Our advanced pentest methodology includes:

Scoping

We work with you closely to define all assets that fall within the scope of the pen test.

Reconnaissance And Intelligence Gathering

We gather publicly available information using open source techniques (OSINT) to build intelligence that could be used to compromise your organisation.

Active Scanning And Vulnerability Analysis

We conduct a full assessment of network infrastructure and applications to obtain a complete picture of your organisation’s attack surface.

Mapping And Service Identification

We research and gather detailed information about target systems.

Application Analysis

We perform an in-depth audit of applications residing on target hosts to identify security vulnerabilities to exploit.

Service Exploitation

We attack identified vulnerabilities to gain access to target systems and data.

Privilege Escalation

We attempt to compromise a privileged account holder, such as a network administrator.

Pivoting

We use compromised systems as a mechanism to attack additional assets.

Reporting And Debrief

We provide a manually-written pentest report that includes an executive summary and recommendations about how to effectively address identified risks.

Case Studies
