External pentest for businesses

External penetration testing - a safe, controlled check of information systems for vulnerabilities that can be exploited for attacks from the Internet.
A pentest is equally important for a large corporation and for a small online store. We monitor new cyber threats daily and promptly take them into account in our tests.

  • External perimeter analysis
    We assess all aspects of your cybersecurity to understand which elements are visible from the outside and how vulnerable they are to attacks. We check for open ports, available services, configurations, and more.
  • Authentication and account verification
    We check whether an attacker can gain access through weak authentication. We test the resilience of login mechanisms: brute-force, weak passwords, lack of 2FA, use of credentials.
  • Detection of vulnerabilities in web apps and APIs
    We identify possible ways of data compromise or service disruption through external interfaces, looking for technical and logical vulnerabilities in publicly accessible web resources and integration points.

Features of external pentest

Such penetration testing is the first line of defense for IT infrastructure. This type of penetration testing most accurately simulates real attacks since it is carried out without access to the corporate network. It can be performed without interfering in the company’s internal processes and without affecting its current operations.

This service is especially important for projects with public websites, VPN gateways, APIs, and other services accessible from the Internet.

  • A basic stage in security assessment. An external pentest is usually conducted first, before internal checks and scanning. It shows how exposed your company is to potential attacks from the Internet.
  • Real attacks - without risk for business. During testing, we simulate the actions of a hacker. We rely on proven frameworks, ensure full confidentiality, and do not affect your operations.
  • Flexibility, experience, and support. We adapt the project to the specifics of your company. We offer free consultations and a retest after fixes, convenient reports, and support throughout the entire process.

Benefits of external penetration testing

Attackers can exploit weaknesses in the external network perimeter to gain access to data, compromise accounts, or hijack server resources. Simulating cyberattacks makes it possible to detect these vulnerabilities in advance, avoid potential losses, and test the effectiveness of security measures.

By ordering external penetration testing from Datami, you get:

  1. Identification of issues invisible during regular scanning - a real picture of the state of your cybersecurity.
  2. A detailed report with the results of digital security assessment, tailored for non-technical specialists.
  3. Prioritized recommendations - which vulnerabilities are critical to fix first, and which can be postponed.
  4. A free retest after fixes - to ensure vulnerabilities are eliminated and the system is protected.
  5. Verification of compliance with security and privacy standards: PCI DSS, HIPAA, GDPR, etc.

Threats detected by external pen testing
Common perimeter vulnerabilities
01.
Vulnerable or open services
Unjustifiably open ports, firewall and VPN misconfigurations allow an attacker to launch external attacks.
example_1
02.
Web application vulnerabilities
SQL injections, XSS, authorization issues, and configuration leaks are common attack vectors through web interfaces.
example_2
03.
Weak authentication and access
Lack of 2FA, weak passwords, and access control errors make the system an easy target for penetration.
example_3
04.
Information leaks
Backups, APIs, or configurations in open access may reveal the internal structure and simplify an attack.
example_4
05.
Weak encryption and certificates
Insecure protocols, self-signed or expired certificates increase the risk of traffic interception.
example_5
06.
Outdated or vulnerable software
Using outdated CMS, libraries, or software with known CVEs makes external compromise easier.

FAQ

The service is relevant for businesses with an important online presence that store confidential data, regardless of scale or industry.

We recommend conducting it at least once a year, as well as after significant changes in the IT infrastructure perimeter: before launching new web applications, after replacing or reconfiguring network equipment, implementing new devices, remote access systems, or perimeter security tools, etc.

All terms are fixed in a commercial proposal agreed with the client before the start. Before work begins, the customer makes a 50% prepayment, and the remaining amount is paid after the project is completed. This approach protects the interests of both parties and ensures that the test is carried out according to the client’s requirements.

No, testing is carried out without interfering with system operations. All actions are agreed upon in advance.

An external penetration testing simulates an attack from the Internet without access to the internal network. An internal one checks what happens if the attacker is already inside.

On average 5–14 business days, depending on the scale and complexity of the infrastructure.

Yes, an external penetration test is included in the requirements of many standards and can be part of an official audit.
