Cisco Meraki


Since 2004, Nomios has been providing companies with its experience as an integrator of Cisco solutions, the world leader in IT. As such, our engineers have developed technical know-how coupled with a mastery of the information systems field that they use to meet our customers' network performance and security challenges by relying on Cisco SD-WAN powered by Meraki technology. It is based on an innovative SD-WAN, managed from the cloud for centralised management of the network, application control and security.

We offer you an overview of these solutions.

The highest possible network performance with simplicity and flexibility

Cisco Meraki's Software-Defined Wide Area Network (SD-WAN) solutions feature a unique synergy of Software-Defined Network (SDN) technologies based on the simplicity of deployment and configuration. This includes multi-site and the scalability of this solution, which is fully managed from the cloud from a comprehensive and intuitive dashboard:

  • Easy to deploy: Cisco Meraki security appliances can be remotely deployed in minutes using automatic cloud provisioning.

  • Easy to manage, view and provide alerts: Intuitive centralised management from the dashboard. Security settings are easy to synchronise across thousands of sites using templates.

  • Savings in deployment and operational costs with SD-WAN functionality built into every device.

  • The flexibility of the solution with customised APIs: the solution includes a comprehensive and robust set of out-of-the-box functionality that can be extended with customised APIs.

MX appliances create a framework for Cisco SD-WAN powered by Meraki by automatically provisioning IPsec VPN tunnels between sites. The Meraki dashboard automatically handles VPN routes, authentication and encryption protocols, and key exchange for all Meraki MX security appliances in an enterprise to create hub-and-spoke or mesh VPN environments.

Application performance management and measurement

Application performance management and measurement are taken to the next level with the ability to notify IT or application managers in real-time when performance drops. This is done simply, quickly and without false positives thanks to intelligent triggers defined by machine learning. These automatically adjust the expected level of performance of web applications based on patterns observed on the client network.

The result is maximum optimisation of network performance for mission-critical applications by using available bandwidth more efficiently without sacrificing data security and privacy.

As a result, Meraki's SD-WAN solutions deliver rapid ROI through ease of implementation, unparalleled reliability, and performance management focused on your core business applications. In addition, they require only a small team, without extensive knowledge, to manage and control all sites, through a unified, centralised cloud-based management console for network, application and endpoint control, and security.

Secure SD-WAN managed in the cloud

Improved threat defence with Cisco SD-WAN technology powered by Meraki

  • Next-generation Layer 7 firewall;

  • File protection with Cisco Advanced Malware Protection (AMP) with Threat Grid sandboxing: unmatched protection against emerging threats;

  • Intrusion Detection and Protection (IDS/IPS) with Cisco SNORT;

  • Sophisticated content filtering to maintain productivity and compliance with business and regulatory requirements;

  • Cisco Meraki single self-provisioning site-to-site VPN: MX security appliances leverage the power of the cloud to automatically configure, monitor, and maintain the VPN;

  • High availability and fault tolerance: Cisco Meraki MX security appliances support multiple layers of built-in redundancy to ensure service integrity: WAN connectivity and appliance availability;

  • Seamless, automated cloud security integration with Umbrella SIG (Secure Internet Gateway): advanced DNS-based security suite, web flow security (Cloud Proxy and Remote Browser Isolation), application control (CASB), and mobile/telework endpoint connection and security

  • The world-renowned security research team, Cisco Talos.

The damage caused by network security breaches can be particularly extensive, with the possibility of the entire IT infrastructure being taken out of service. They can represent a considerable financial drain and result in a significant loss of productivity.

In the age of morphing viruses, it is critical to have a security solution that can adapt to the evolving threat landscape and not just block malware but provide the deep visibility that is essential for effective network security. As such, Cisco SD-WAN powered by Meraki technology incorporates an unparalleled threshold of security.

Cisco Advanced Malware Protection (AMP)

AMP Cloud combines a world-class malware database with state-of-the-art monitoring with contextual reporting and retrospective malware analysis to provide an anti-malware solution that ensures complete security before, during and after a malware attack.

The advanced malware protection solution is designed to effectively prevent, detect and remove all forms of threats from computer systems: ransomware, Trojans, spyware, adware, etc. including oligomorphic, polymorphic and, more recently, metamorphic viruses, which escape detection by traditional antivirus software.

Most antivirus offerings require complex configuration and management, but the highly automated Cisco Advanced Malware Protection solution does not. It provides prevention and response to security alerts from an intuitive and highly automated dashboard.

Easy to deploy and manage

  • Enable the best malware protection with just two clicks.

  • Configuration and reporting natively integrated into the Cisco Meraki Cloud Dashboard.

  • Gain visibility with Security Center: Get a quick and easy summary of threats across your networks, or full information about a particular threat.

Detect, identify and prevent malware damage

  • Automatic protection against millions of malicious files: blocking malware in real-time before it can cross the network perimeter.

  • Automatic alerting for retrospective malware detection if a file is discovered to be malicious after it enters the network.

The power of Cisco Networking with Talos

SD-WAN powered by Meraki is natively integrated with advanced security through Cisco Talos. The strength of Cisco Meraki's offerings lies in this elite security research team. Talos powers the world's largest malware detection network. State-of-the-art prevention technologies are at work every day to identify, assess, and effectively respond to hacking activity, intrusion attempts, malware, and all other kinds of vulnerabilities.

Talos numbers

  • 1.5 million instances of malware analysed every day;

  • 7.2 trillion attacks aborted each year.

The system guarantees advanced protection even against new and emerging threats. This is the strength of the community of a market leader like Cisco. In addition to Cisco's analysis, the community's efforts to keep up to date by detecting new signatures are essential. MX appliances also receive automatic security updates, ensuring secure WAN traffic.
