IT Security for Businesses:
Protecting Networks, Identities and Access

Network, identity, access and endpoint security, combined into a traceable security concept for day-to-day operations.

About this service

Security that works in operation

IT security in a business protects networks, identities, access, endpoints and cloud services against unauthorised access and outages: with firewalls and segmentation, multi-factor authentication, secure remote access, endpoint protection and logging. We plan and implement it across vendors, including Cisco, Fortinet, Sophos, Palo Alto Networks and Microsoft.

Vendor-independent in planning, technically sound in execution and traceably documented. We factor in the relevant requirements from ISO 27001 and NIS2 wherever they apply to your environment and your area of responsibility.

Typical scenarios

When we can support you

Distributed IT environments, more complex access requirements and increasing demands create a need for clearly governed security in day-to-day operations.

Cloud and hybrid environments

Cloud services have become part of everyday business while users, devices and locations are increasingly distributed.

External access and remote work

Employees, service providers and branch offices regularly access internal business resources from outside the organisation.

Audit and compliance requirements

Technical security measures must remain verifiable, reviewable and aligned with internal or regulatory requirements.

Historically grown security architecture

Years of accumulated rules, permissions and isolated solutions make it difficult to assess the current level of protection reliably.

Growth and system changes

New locations, applications and cloud services expand the attack surface and increase technical dependencies.

Security incidents and suspected threats

Unusual sign-ins, phishing attempts or suspicious data traffic create an immediate need for investigation and may put operations at risk.

FREQUENTLY ASKED QUESTIONS

Questions about IT security

What does an IT security project cost?

The effort depends mainly on the number of sites and firewalls, the number of users and identities, existing licences, the size of the current rule base and any evidence required for audits. After a short assessment of your environment you receive a fixed price for the chosen package.

Do you support NIS2 and ISO/IEC 27001?

Yes, with the technical implementation: access control, segmentation, MFA, encryption, logging and operations documentation. Whether your organisation falls under NIS2 or is compliant is not something we assess; that remains the task of your organisation and your legal advisers.

Can you work with our existing solutions?

Yes. We work across vendors, including Cisco, Fortinet, Sophos, Palo Alto Networks and Microsoft, and use existing licences where they make technical sense.

Will introducing MFA or NAC disrupt daily work?

We start with a small pilot group, clarify exceptions for devices and accounts in advance and then roll out step by step. This keeps sign-ins and access predictable for your team.

Do you also review our existing firewall configuration?

Yes. In the security assessment we assess the rule base, exceptions and hardening of your firewalls and show which rules are redundant, too open or no longer traceable.
