Proactive Threat Mitigation

Growing threats on information systems are a today a major issue for company and governments all around the world.

Cybercriminals are using a variety of sophisticated techniques to break into computer network, compromise sensitive assets and disrupt business operations. The consequence of these incidents can be catastrophic, ranging from loss of critical data to disruption of business operations, loss of reputation and customer trust.

Identify and address vulnerabilities before malicious actors do, bolstering cybersecurity defenses and reducing the risk of data breaches.

Pentest: External assets discovery

Managing the complete array of IP addresses, virtual hosts, domains, and sub-domains accessible on the Internet can be a challenging task for any company, especially for larger enterprises with multiple IT teams. Do you wish to regain control over your assets available on the Internet?

External mapping: Main challenges

What are the challenges to ensure the safety of assets published on the internet on in the cloud:

  • Maintain up-to-date documentation for all servers published on the Internet or through Cloud services
  • Identify and ensure only necessary services are accessible from the internet.
  • Verify that test, development, or preproduction servers are not accessible externally.
  • Implement control measures for new assets during mergers or acquisitions.
  • Foster collaboration among IT teams to minimize configuration errors and prevent unauthorized access to resources from the internet.

External mapping: Our Solutions
