External Network Penetration Testing Services
Identify critical vulnerabilities before attackers do. Our external network penetration testing services uncover security gaps and provide fast, easy and actionable solutions to protect critical assets from cyber threats.
More than 54% of companies use penetration testing to check their networks for vulnerabilities. External penetration testing services simulate real-world attacks on internet-facing assets within an organization, exposing their vulnerabilities in web applications, APIs and network infrastructure. At Astro, we combine manual and automated vulnerability scanning to quickly and fully identify any security weaknesses that could be exploited by external attackers. We then deliver actionable solutions and guidance that fully safeguard your assets against evolving cyber threats.
Achieve Critical Cybersecurity Objectives
Astro applies industry-standard methods of ethical hacking to test your network from the perspective of an external malicious actor. Through this, you can achieve:
The main purpose of external penetration tests is to find flaws in firewalls and unpatched systems. These are critical exploit points where bad actors will attack, so by fixing them regularly, organizations reduce their risk of a breach. External tests reveal web application security vulnerabilities (such as XSS), but also focus on misconfigurations, open ports, exposed services and other externally exploitable weaknesses.
Healthcare, fintech and government sectors require regular security testing to comply with HIPAA, GDPR, PCI-DSS and other regulations. This is most easily achieved with an external penetration test company like Astro that demonstrates due diligence, satisfies audit demands and is experienced with what is needed to avoid penalties from non-compliance.
By proactively detecting and stopping threats, you are better able to reassure clients, investors and partners of your commitment to security. By the time you have a breach, the reputational damage will already be done. Transparent reports to all relevant stakeholders help generate confidence in your ability to safeguard sensitive data and operations.
Astro’s external pen testing engagements provide more predictable costs than other security offerings, with no hidden fees or surprise expenses. Our reporting is based on prioritizing remediation based on risk severity. This allows for strategic allocation of resources to address high-impact vulnerabilities first, maximizing your ROI on cybersecurity investments.

Astro’s Proven Four-Step Delivery Process
Our external penetration testing services follow a rigorous battle-tested approach that rapidly empowers our clients with actionable remediation strategies.
We begin with collaborative workshops involving your IT, security and compliance teams. Together, we map your company’s internet-facing assets such as public IP ranges, domains, cloud environments, APIs, and web applications, to define the right testing boundaries for your infrastructure. During this phase, we also clarify compliance requirements.
Our methods involve a combination of Microsoft-powered tools and proprietary workflows. Our external penetration testers perform manual reconnaissance, mapping network infrastructure and probing DNS configurations to uncover more subtle misconfigurations that can be exploited in your network.
Our testers simulate various real-world attacks to exploit identified vulnerabilities. Some of these techniques include phishing simulations, cross-site scripting (XSS) attacks on web apps, and privilege escalation in cloud environments. We are also able to mimic the exploits of nation-state APT groups and ransomware operators.
Once our testing is complete, we provide clients with encrypted, jargon-free reports organised in order of risk severity (critical, high, medium). Each finding in the report includes proof-of-concept exploit details, CVSS scores, and prioritized remediation guidance. For ongoing support, Astro also offers retainer services by our external security penetration testing consultants who validate fixes, update security policies, or serve as virtual SecOps extensions.
