Release of the solution SASE

In June, 2020 Cisco entered the market of solutions for protection of peripheral calculations. It is about so-called boundary services of secure access of SASE (secure access service edge).

The term SASE was entered by analysts of Gartner for designation of the technologies combining network services and services of security — the program configured geographically distributed networks (SD-WAN), web gateways (SWG), brokers of secure access into a cloud (CASB), protection of DNS and cloud firewalls.

Cisco entered the market of solutions for protection of peripheral calculations

Though Cisco has a set of types of SD-WAN, the company had no SASE technology. With a release of the version of Cisco SD-WAN 17.2 it changed with a release of the solution Cisco SD-WAN + Umbrella. It represents solution integration for distributed networks of SD-WAN with  cloud services of security of Umbrella Cloud Security. The cloud computing architecture of services of security Umbrella saves from  need to manually build protection of network infrastructure separately for each branch of the company, the producer claims.

In addition to DNS addressing security Umbrella services began to perform functions of firewalling of new generation (NGFW). Via the vManage console of the solution SD-WAN each branch and  mobile users can appoint the IB-special configuration the politician.

To COVID-19 pandemic interest in SASE was rather low. By estimates of analysts, implementation of these technologies in broad application was expected not earlier, than in 5-10 years. But the situation sharply changed after the outbreak of a coronavirus which led to mass transition to remote work and increase in load of communication channels and data processing centers.

The new solution of Cisco User Defined Network is intended for locations in  which for the user access the single wireless network is used (campuses, hospitals, hotels  , etc.).^[1]

Cisco SD-WAN Security

On November 14, 2018 the Cisco company reported that it integrates technologies of software-defined global networks (software-defined wide area network, SD-WAN) and information security to help the organizations quickly, effectively and to safely use cloud computing.

As noted in Cisco, networks WAN undergo radical conversions. The modern organizations place the applications in different clouds – public private and on model "software as service" (SaaS). Users are connected to network not only of office, but also being, for example, in cafe or in the airport waiting room. In order that employees could use crucial business applications, the organizations should rely on network Internet. As a result on cloud border issues of network interaction and information security support closely intertwine.

Before the solution SD-WAN forced to select IT specialists between functionality of applications and information security. According to the developer, the solution Cisco SD-WAN differing in simplicity and scalability will help IT personnel to improve experience of use of applications, to increase productivity of users and to implement technologies of information security everywhere where it is necessary: from branch of the company to all cloud.

According to the statement of the developer, in the solution Cisco SD-WAN are implemented:

• Alloy of information security and SD-WAN. Advanced technologies of information security, an intrusion prevention system and the firewall of a corporate class taking into account requirements of applications, filtering of URL are built in Cisco SD-WAN devices; all control is exercised on a centralized basis. Cisco SD-WAN completely is based on an intelligent system of information security of Talos.
• Simplification of procedures of information security. Integration of the solutions Cisco SD-WAN and Cisco Umbrella allows to block the harmful addresses even before connection establishment.
• Functionality of applications. Cisco and Microsoft companies improved for users functionality of Microsoft Office application 365. Cisco SD-WAN in real time traces all available routes to a cloud of Microsoft Office 365 and defines the next cloud using the addresses Microsoft Office therefore high-speed performance for users increases up to 40%.
• Openness and programmability. Existence in the solution Cisco SD-WAN of open interfaces of application programming of API gives to partners and service providers an opportunity to create new services. For the aid to developers and network engineers in community Cisco DevNet the training laboratories on SD-WAN and "sandboxes" are open.
• The updated infrastructure SD-WAN. SD-WAN based on technologies Viptela and Meraki, expands with Cisco the choice of users even more, offering two integrated router ISR (Integrated Services Router), developed for small and large branches.
• Service of quick start. Helping customers to accelerate deployment of SD-WAN and to reduce risks, Cisco offers service of quick start of SD-WAN Quick Start. The service is provided on the fixed price, for project implementation simplification customers get access to opportunities of remote installation and knowledge transfer.
• Simplicity of acquisition and management. Cisco as much as possible simplified processes of application of the solution and management of it. Both technologies, network and information security, are purchased under one license, control of them is exercised using the single interface.

The software of Cisco SD-WAN Security and Microsoft Office 365 is available since the beginning of the 4th quarter 2018.

Premiere of the solution Cisco SD-WAN

On October 23, 2018 the Cisco company presented the solution Cisco SD-WAN, within the concept of the intentsionno-focused networks which cornerstone developments of Cisco on creation of a system capable to expect actions are, to neutralize in a security risk germ and also to be improved and study continuously.

The SD-WAN technology is intended for creation of the scalable distributed corporate networks. Its feature is separation of levels of transport and control that allows remote branches to manage on a centralized basis transport networks, noted in Cisco.

According to the statement of the developer, implementation of Cisco SD-WAN will allow customers to accelerate process of connection of new branches and to reduce the accompanying costs and also to optimize expenses on channels from telecom operators. This solution gives the chance to configure terminal units in remote branches clicking of the button at the central office. One more key difference of Cisco SD-WAN – the high level of security from cyberthreats which is provided with the built-in segmentation, enciphering, support of logical topology, service points and also external means of cybersecurity. As a result time of detection of threats in network decreases repeatedly that minimizes potential losses of the companies from data loss and costs for recovery of information, claim in Cisco.
