Why network security and availability are critical
Modern organisations depend on always-on connectivity. Even short periods of network disruption can halt operations, impact customers, and damage reputation.
Network-based attacks are no longer limited to simple intrusion attempts. Attackers increasingly focus on service disruption, exploiting misconfiguration, overwhelming connections, or targeting exposed services. DDoS attacks, in particular, are designed to make services unavailable rather than steal data — causing maximum operational impact with minimal effort.
Without robust network security and resilience in place, organisations remain vulnerable to outages as well as attack.
The modern network threat landscape
Network threats have evolved significantly in recent years:
- DDoS attacks have increased in frequency, scale, and sophistication
- Internet-facing services are constantly scanned for weaknesses
- Misconfiguration remains a leading cause of exposure
- Cloud and hybrid networks increase complexity and attack surface
- Remote access expands the number of potential entry points
These threats affect organisations of all sizes and are no longer limited to high-profile targets.
Why basic network protection is no longer enough
Traditional network security often focuses on perimeter firewalls and basic access controls. While these remain important, they are no longer sufficient on their own.
Common limitations include:
- Limited visibility into network traffic and behaviour
- Inadequate protection against volumetric or application-layer DDoS attacks
- Firewalls that are poorly configured or rarely reviewed
- Lack of monitoring for abnormal traffic patterns
- Minimal resilience planning for connectivity loss
As a result, organisations may remain operationally exposed even when basic security controls are in place.
What effective network security should deliver
A modern network security approach should provide:
- Strong protection for internet connections and hosted services
- Defence against network-based attacks and service disruption
- DDoS mitigation to maintain availability under attack
- Visibility into traffic patterns and potential threats
- Secure access for users, systems, and external services
Above all, network security must prioritise availability as well as protection.
How BSAS approaches network security and DDoS protection
BSAS delivers network security as a managed, resilience-focused service.
We start by reviewing network architecture, connectivity, and exposure — identifying risks to availability and security. From there, we implement layered controls that protect services, filter malicious traffic, and reduce the impact of attacks.
Our approach focuses on keeping services online and accessible, even during hostile or high-traffic events.
Key capabilities of BSAS network security solutions
Depending on your environment and requirements, our services include:
- Secure configuration of firewalls and network gateways
- Traffic filtering and threat prevention controls
- Protection for internet connections and hosted services
- DDoS detection and mitigation
- Monitoring of network performance and anomalies
- Ongoing management and optimisation
These capabilities work together to protect connectivity and maintain service availability.
Why BSAS is different
Many providers deploy network security controls and leave them untouched for years. Configuration drifts, threats evolve, and responsibility becomes unclear when disruption occurs.
BSAS takes ownership of network security by:
- Designing protection around availability and resilience
- Actively managing and reviewing network security controls
- Monitoring traffic and performance for early warning signs
- Responding quickly to incidents and abnormal behaviour
- Integrating network security with wider cyber services
This results in more resilient networks, fewer outages, and faster recovery when issues arise.
How network security fits into a layered strategy
Network security is a critical layer within a wider cyber security approach. When combined with:
- Email security
- Endpoint protection
- Microsoft 365 security
- Backup and recovery
- Security awareness training
…it helps prevent attacks from spreading and ensures services remain available even under pressure.
Who this service is for
Network Security & DDoS Protection is particularly important for organisations that:
- Depend on reliable internet connectivity and hosted services
- Expose applications or services to the internet
- Need protection against DDoS attacks or service disruption
- Support remote users or external access
- Want greater visibility and control over network traffic
Moving beyond perimeter-only security
Modern networks require active protection, monitoring, and resilience planning — not just static firewall rules.
BSAS helps organisations protect connectivity and maintain availability by delivering network security and DDoS protection as part of a managed, layered cyber security strategy.
