Testing Service
What is penetration testing?
Penetration testing, or pen testing, is an ethical cybersecurity exercise that identifies and safely exploits vulnerabilities in systems, applications, and websites. By applying the same tools and techniques used by real attackers, pen testing simulates genuine attack scenarios, offering actionable insights to strengthen defenses.
Engaging in a penetration test helps organizations proactively reduce security risks and enhance cyber resilience by uncovering and addressing weaknesses before malicious actors can exploit them.
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
01
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
02
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
03
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
04
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
05
Additional Vulnerabilities
Beyond the core categories above, our penetration testing also uncovers:
- Broken access controls allowing unauthorized privilege escalation
- Business logic flaws that let attackers bypass normal workflows
- Insufficient input validation leading to injection attacks
- Directory traversal and file inclusion vulnerabilities
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:
- A comprehensive breakdown of all risks discovered
- An explanation of the business impact associated with each issue
- Insight into the likelihood and ease of exploitation
- Practical, step-by-step remediation guidance tailored to your environment
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:
01
Scoping
We work with you closely to define all assets that fall within the scope of the pen test.
02
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.
03
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.
04
Mapping And Service Identification
We research and gather detailed information about target systems.
05
Application Analysis
We perform an in-depth audit of applications residing on target hosts to identify security vulnerabilities to exploit.
06
Service Exploitation
We attack identified vulnerabilities to gain access to target systems and data.
07
Privilege Escalation
We attempt to compromise a privileged account holder, such as a network administrator.
08
Pivoting
We use compromised systems as a mechanism to attack additional assets.
09
Reporting And Debrief
We provide a manually-written pentest report that includes an executive summary and recommendations about how to effectively address identified risks.

Frequently Asked Questions
What is penetration testing as a service (PTaaS)?
PTaaS provides continuous penetration testing delivered through a platform. Instead of a one-time test, businesses get ongoing assessments, real-time reporting, and regular updates to keep security strong.
What happens after pen testing is completed?
You receive a detailed report outlining vulnerabilities, the level of risk, and recommended fixes. Our team can also provide guidance or hands-on support to remediate issues.
Can a pen test be performed remotely?
Yes. Most penetration tests can be conducted remotely using secure methods. For on-site testing (such as physical security assessments), a team may need to visit your location.
Should I use the same penetration testing supplier?
Using the same supplier ensures they understand your systems, but it’s also wise to occasionally get a fresh perspective from another provider to uncover new insights.
Will a pen test affect business operations?
No. Tests are carefully planned to avoid disruption. They simulate attacks in a safe environment, and our team communicates with you throughout the process.
How much does a pen test cost?
Costs vary depending on the scope, size, and type of testing. Smaller tests may start from a few thousand dollars, while large enterprise-level tests cost more. The investment is far less than the cost of a real breach.
