-
Access control
Excessive permissions accumulated over time without review
-
Assessment findings
Assessments identified security or configuration weaknesses
-
Pen test results
Penetration testing identified exploitable weaknesses

How Security Hardening is performed
Every Security Hardening engagement is tailored to the organization's environment, priorities, and operational requirements to ensure effective implementation with minimal business disruption.
-
Tailored approach
Security Hardening is planned individually for each organization based on its infrastructure architecture, cloud and remote access environment, operational requirements, existing technologies, and remediation priorities.
-
Flexible scoping
The implementation scope may be defined using the results of a Security Assessment or Penetration Testing, based on client-defined requirements, or through a preliminary scoped technical review when additional clarification is needed.
-
Controlled execution
Implementation activities are planned and coordinated with the client’s team, taking into account technical dependencies, available resources, operational constraints, and business requirements. This approach helps minimize disruption to production systems and day-to-day operations.

-
Engineering experience built through transformation projects
![Engineering experience icon]()
Ispirer develops its own products for database and data migration, as well as code conversion, including SQLWays, Ispirer Data Migrator, and CodeWays. Through these projects, our teams regularly work with environments of different scales and complexity – where access management, configuration consistency, operational processes, and security controls often require careful review and improvement alongside the technical implementation itself.
This experience is complemented by Ispirer’s ISO/IEC 27001 certification and our own implementation of security practices within the company. We maintain established security controls, operational processes, and continuous improvement practices in our own environment.

What is Security Hardening?
Security Hardening is the process of reducing the attack surface and security exposure of systems, cloud services, and networks by improving system configurations, strengthening access controls and authentication mechanisms, enforcing security policies, and implementing secure operational practices aligned with industry best practices.
How is Security Hardening different from Security Assessment?
Security Assessment is used to identify vulnerabilities, security gaps, misconfigurations, and areas of risk. Security Hardening focuses on implementing changes that address those findings. While an assessment answers the question of what should be improved, hardening focuses on making those improvements within the environment.
Do we need a Security Assessment before Security Hardening?
We generally recommend conducting a Security Assessment before Security Hardening, as it helps identify gaps, prioritize remediation efforts, and ensure resources are focused on the most critical areas. However, if the areas requiring improvement are already known, implementation activities can be planned and initiated directly.
How can Security Hardening be safely performed in production environments?
The safety measures for performing Security Hardening within active production environments include careful preparation and planning, adherence to change management processes, and gradual implementation.
What environments can be hardened?
Security Hardening can be applied across on-premises and cloud infrastructure, Microsoft Azure, Amazon Web Services, Google Cloud Platform, Microsoft 365, Google Workspace, network and endpoint environments, remote access solutions, firewalls, and identity and access management systems. The scope is tailored to the organization’s technology landscape, security objectives, and remediation priorities.
How long does a Security Hardening project take?
Security Hardening timelines depend on the agreed scope, environment complexity, number of systems involved, implementation priorities, and coordination requirements. Targeted hardening activities, such as specific configuration improvements or security control implementation, may take several days, while broader initiatives involving multiple systems, infrastructure areas, and operational processes are typically completed over several weeks.
