Why implement a PAM solution in your organization?

What is bastion host ?

Every organization, private or public, hosts critical servers containing sensitive data and essential business applications. Ensuring business continuity and long-term sustainability requires strict control over who accesses them, how, and when.

This is precisely the mission of an administration bastion solution: to ensure security, control, and traceability of sensitive access.

The bastion acts as an access portal, a single, secure, and supervised entry point through which privileged accounts connect to critical assets (servers, network equipment, applications, cloud environments, etc.), whether via SSH, RDP, or HTTPS connections.

Deploying it within an organization immediately provides full visibility across all access, regardless of the environment involved.

It is now considered a key element of cybersecurity, as it serves as an essential barrier against cyberattacks, human errors, and privilege abuse, while delivering visibility and compliance.

Who are privileged users?

Privileged accounts are held by individuals or identities with elevated rights, allowing them to access critical systems, modify sensitive configurations, or manage the organization's security and data.

These profiles represent a major cybersecurity challenge, as their compromise can grant near-total control over the information system.

1. Access Control & Restriction

This cybersecurity solution creates a centralized, secure entry point for managing access to sensitive assets. Only authorized accounts can authenticate to the bastion, reducing the risk of unauthorized access. Every session from a privileged account must be clearly identified, with access restricted to the relevant perimeter only, and time-limited if needed (specific dates, time slots, etc.). Access can also be restricted to specific source IP addresses.

2. Risk Reduction

By limiting access to critical and sensitive systems, the bastion significantly reduces the risk of abuse, hacking, or data exploitation. Even if a privileged account were compromised, the attacker would only have access to the resources associated with that specific profile, limiting the potential damage compared to broad or unrestricted permissions.

3. Traceability & Auditability

All activities performed through the bastion are systematically recorded, providing full traceability of actions taken by administrators and external contributors. The ability to track and audit every session is critical for detecting suspicious behavior, investigating security incidents, and meeting regulatory requirements (GDPR, NIS 2, ISO 27001, etc.).

4. Enhanced Protection of Sensitive Data

By routing all traffic through the bastion, access to sensitive data is better protected. The solution leverages secure communication protocols (RDP, SSH, HTTPS, etc.) and storage mechanisms that ensure confidentiality, integrity, authenticity, and non-repudiation, every data flow transits through a controlled, auditable channel.

5. Access Rights Management

The bastion enables granular access rights management. Each user profile is granted only the access required to perform their specific tasks, in line with the principle of least privilege. In practice, this prevents a privileged account from initiating connections to all machines across the organization — and by extension, prevents an attacker who has hijacked that account from doing the same.

6. Insider Threat Prevention

By enforcing multi-factor authentication and restricting permissions based on each user's profile, the bastion helps reduce the risks posed by insider threats, whether intentional or accidental.

7. Simplified Account Management

Centralizing access through the PAM solution streamlines account and rights management. Adding, modifying, or revoking access is handled from a single point, improving operational efficiency, especially for SMEs whose IT teams are often stretched across multiple priorities.

8. Regulatory Compliance

Many regulations and security frameworks (GDPR, NIS 2, DORA, ISO 27001, etc.) require strict access controls to be in place. An administration bastion helps organizations achieve and maintain compliance with these requirements.

Example: any action performed by an admin profile on a critical server must be monitored, recorded, and easily traceable.

9. Credential & Secret Management

The bastion includes centralized management of credentials, passwords, and secretss, notably through a built-in credential vault. This strengthens security by preventing unauthorized disclosure of authentication information, which remains one of the most common sources of compromise.

10. Risk Isolation

By isolating privileged access, the PAM/bastion solution significantly reduces the attack surface. Even in the event of an account compromise, the potential damage remains contained — a particularly critical capability for any organization looking to adopt a Zero Trust security posture.
