What are Penetration Testing Services?

Penetration Testing Services are crucial for organisations that want to take their cyber security seriously.

A penetration testing service, also known as a pen testing service, is a type of offensive security test that is carried out to discover and exploit potential vulnerabilities in an organisation’s technical systems. They involve scrutinising internal IT systems, and exploring anything from an organisation’s network infrastructure to their web applications, all intending to identify vulnerabilities.

Pen tests tend to blend automated and manual testing techniques to simulate real-world attacks and discover active security weaknesses.

WHAT ARE THE BENEFITS OF PENETRATION TESTING?

Why does your organisation need a penetration test?
Identify Vulnerabilities: pinpoint security weaknesses in networks, infrastructure, web applications and devices before the hackers can.
Enhance your security measures: strengthen existing security protocols by finding weaknesses.
Compliance Assurance: Regular pen testing helps ensure compliance with industry standards and regulations, reducing legal and financial risk.
Protect Critical Assets: Security testing finds cyber risks in your important business assets, helping you safeguard against data breaches or losses.
Cost-Effective Security Strategy: Mitigating vulnerabilities early effectively reduces the risk of security breaches and the financial and reputational costs that come with them. The penetration testing cost is far less.
Bolster Cyber Defences: prepare and improve defences against ever-evolving cyber threats and attacks.
Gain Trust: Build stakeholder, partner and customer confidence by demonstrating a commitment to security through regular pen testing.
CREST & CHECK Certified: Using CREST and CHECK certified penetration testers ensures an ethical and thorough test to high standards.
Customisable testing scope: Penetration testing services can be tailored to your business-specific needs. Target important areas or assets such as cloud systems or web applications.
Detailed report: Stipe OLT’s pen testing services provide detailed reports with actionable insights that aid in strategic security planning and implementation.

Penetration Testing FAQs

What is penetration testing and how can it protect my business?
Penetration testing, also known as ethical hacking or pen testing, is a proactive security assessment technique conducted to identify vulnerabilities and assess the effectiveness of an organization’s security controls. It involves simulating real-world attack scenarios to evaluate the security posture of an organization’s networks, systems, applications, or infrastructure.

Penetration testing is a vital tool for organisations as it uncovers security weaknesses in an organization’s infrastructure, applications, or network configurations. It tests for vulnerabilities, like software flaws or misconfigurations, providing insights into potential entry points for attackers. Critically, it assesses the effectiveness of security controls such as firewalls, intrusion detection systems, and access controls, weaknesses or gaps can be identified and addressed to strengthen overall security.

As Penetration testing is key to securing your systems, be sure to choose tried and tested penetration testing providers, especially CREST-accredited ones as they offer backed services and have the technical expertise to find the complex vulnerabilities that modern attackers will exploit.
