Offensive Security. Uncompromising Defense.

Internal pentesting

Internal Penetration Testing simulates an insider threat scenario — where a user with physical or logical access attempts to compromise internal systems. This ethical hacking method helps organizations discover what vulnerabilities may be exploited by employees, contractors, or attackers who’ve breached the perimeter.

Enterprise Wireless pentesting

Wireless penetration testing simulates attacks on your wireless networks to evaluate how secure your access points, encryption protocols, and internal segmentation are. By identifying misconfigurations or weak defenses, we help prevent unauthorized access from outside and ensure guest and employee networks are fully isolated.

External pentesting

In the dynamic landscape of cybersecurity, External Penetration Testing emerges as the vigilant guardian of your digital fortress. Businesses recognize the critical importance of fortifying their external defenses against evolving threats— not just to protect data, but to strengthen trust with clients, partners, and stakeholders.

Internal Vulnerability Assessment (IVA)

Internal Vulnerability Assessment (IVA) is the process of identifying, defining, and classifying security weaknesses in your internal network, computer systems, and communications infrastructure. It helps organizations understand where real internal business risks lie, what needs to be addressed, and how. Proactively detecting internal threats boosts your organization's ability to defend and builds customer confidence.

Approved Scanning Vendor (ASV)

All entities including merchants, service providers and financial institutions must get a quarterly scan completed to remain compliance with the PCI DSS standards.

Web Application pentesting

A Web application (Web app) is an application program that is stored on a remote server and delivered over the Internet through a browser interface. Web apps process sensitive data such as user and financial information, making them frequent targets for cybercriminals. As web apps grow more complex, the range of exploitable vulnerabilities increases.

Web Services & Api pentesting

Web services and APIs form the backbone of digital platforms — from mobile apps to cloud-native systems. While they offer speed and flexibility, they can also expose sensitive functions if not secured properly. GTIS's API and Web Services penetration testing helps you identify and remediate vulnerabilities before they're exploited...

Mobile Application pentesting (Android & iOS)

Mobile apps play a critical role in modern business and everyday life — from banking to healthcare. But the growing data they handle also makes them high-value targets for hackers. As new vulnerabilities emerge, it’s essential to proactively secure your mobile platforms.

Windows POS

Point-of-Sale (POS) systems are critical to retail and hospitality. Windows-based POS environments require specialized penetration testing to ensure payment data and customer information remain secure against modern threats.

Android POS

Modern Android POS systems bring flexibility but also new attack vectors. We conduct deep-dive penetration testing on Android-based POS architectures to secure transactions and protect sensitive data from compromise.
