Gateway & Perimeter Security

How secure are the entry points to your corporate network? We protect communication channels, internet access and network boundaries with intelligent security mechanisms, continuous monitoring and modern access concepts.

Why gateway & perimeter security is crucial

The classic network boundary barely exists anymore in hybrid IT landscapes. Employees access applications in data centres and cloud platforms from various locations, while external partners and mobile devices communicate continuously with corporate networks. This creates new attack surfaces and classic perimeters lose their significance. Modern gateway and perimeter security concepts combine firewalls, secure web gateways, Zero Trust Network Access (ZTNA), network segmentation and identity-based access controls into an integrated security architecture. This way, access is continuously verified, applications are specifically protected and attacks are prevented as early as connection setup.

Challenges faced by our clients

Missing visibility over network access

External connections and data flows can only be monitored and controlled to a limited extent.

Insecure internet and remote access

VPN, cloud and remote access connections significantly expand the attack surface.

Security solutions operate in isolation

Firewalls, web filters, cloud security and identity management are often operated separately and offer no consistent security level.

Attacks spread within the network

Missing network segmentation makes it easier for attackers to spread further within the IT landscape after a successful compromise.

Our services

Security analysis

We assess network architectures, communication channels, internet access and remote access, and identify risks as well as optimisation potential.

Security architecture

We develop integrated gateway and perimeter architectures that intelligently combine firewalls, secure web gateways, Zero Trust Network Access (ZTNA), network segmentation and identity management.

Implementation

We implement firewalls, secure web gateways, VPN/ZTNA solutions and further security components seamlessly into your infrastructure.

Identity-based access control

Users are granted access exclusively to the applications and resources they actually need. Identity, device status and security policies form the basis of every access decision.

Continuous monitoring

Network events and communication flows are continuously monitored and assessed to detect threats early and contain them in a targeted way.

Ongoing optimisation

Through ongoing optimisation of rulesets, policies, signatures and security configurations, we ensure a permanently high security level.

Integrated security architecture

Many companies operate firewalls, secure web gateways, VPN and cloud security solutions as separate individual solutions. We integrate these components into a consistent security architecture in which network access, identities, cloud services and security policies work together intelligently. This creates a security level that adapts flexibly to new requirements and threats.

Security by design for modern corporate networks

Modern gateway and perimeter security is not created by individual security solutions, but through their intelligent interaction. We combine various protective mechanisms into an integrated security architecture that secures network access, detects threats early and consistently controls access to applications and data.

Secure Web Gateway

Protects internet access and blocks malicious content as early as connection setup.

Firewall & Threat Prevention

Detects and prevents attacks at the network level through intelligent security mechanisms.

Zero Trust Network Access

Grants access exclusively to authorised users for approved applications.

Secure remote access

Enables protected connections for employees, sites and external partners.

Network segmentation

Limits the spread of attacks by separating business-critical network areas.

Central security policies

Control network access, user rights and security requirements consistently across the entire IT landscape.

Our contribution to your success

We create a gateway and perimeter security architecture that consistently secures external access, controls communication channels and stops threats already at the network boundaries. This reduces your IT's attack surface, creates visibility over data traffic and enables secure connections between employees, sites, cloud platforms and business partners - without restricting daily collaboration.
