Isolation of legacy systems with SPSA

Executive Summary

Skillplan Secure Access enables controlled and secure isolation of legacy systems that still need to be operated.

The Zero Trust architecture ensures that only authorized users and applications are granted access, while all other connections are blocked or monitored.

Challenge:

Legacy systems that can no longer be patched are a preferred target for cyber attacks. Unclosed security gaps act as a catalyst for attacks and expose companies to high risks.

Solution:

Skillplan Secure Access (SPSA) provides a centralized security solution for legacy systems through isolation and micro-segmentation.

SPSA prevents direct network connections to vulnerable systems, thus significantly minimizing the attack surface and at the same time enabling secure, efficient administrative access.

Appliance

As a hardware appliance or VM for Hyper-V or ESX.

Multi-factor authentication (MFA)

MFA for local appliance users or with Active Directory integration to increase NIS2 compliance.

Fine control of the data flow

  • Rule-based filtering of incoming and outgoing connections.
  • Restriction of data traffic to authorized applications and users.
  • Complete logging of all interactions with the legacy system.

Measurable results

  • Secure continuation of critical legacy systems despite the lack of security updates.
  • Transparent control of all access and data flows.

Cost savings

  • No need to rush into replacing old systems.
  • Reducing the risks and costs of potential cyber attacks.

Risk minimization

  • Elimination of direct network connections to legacy systems.
  • Protection against malware and ransomware through isolated access mechanisms.
