Why Network Visibility Is The Key To A Secure Cloud Environment

Let’s talk trends. As of this very moment, 93% of all US & EMEA organizations are using at least one cloud-based technology. Public cloud revenue is expected to grow from $146 billion (2017) to $236 billion by 2020 as companies increasingly transition from a cloud-first to a cloud-only strategy. In fact, the new industry standard is the use of multiple clouds and most enterprises are already opting for a hybrid cloud environment. Moreover, between 67% and 75% of companies are estimated to be using a hybrid cloud structure. These numbers are growing rapidly as businesses look to leverage the benefits of both, the more stable private cloud as well as the more flexible and scalable public cloud. However, as the majority of global companies move to the cloud, the question of security still remains.

Cloud advantages

Whether it’s AWS, Azure or Google Cloud, the cost of having your services in the cloud is reducing, and the ability to save IT expenditure is probably the main driver behind the global trend to shift more and more services and data into the cloud. IT budgets receive another boost through cloud technology usage as its costs typically fall under operating expenditure (OPEX) instead of capital expenditure which allows for more financial flexibility.  As a result, cloud technology allows companies with less resources to get access to the best technology previously only available to big enterprises.

Cloud computing offers several advantages to businesses

Besides the obvious cost-related benefits, there are several other advantages of using cloud technology: improved performance, ease of maintenance and access, simpler administration, high availability and increased efficiency. In general, all the aforementioned perks lead to one crucial reasoning: businesses need to leverage the cloud as it makes IT more flexible and scalable in order to keep up with today's fast-paced world.

Security issues

Despite the rise of cloud technology application in business, there are still many major concerns related to its rapid proliferation throughout the enterprise, most importantly: security. For companies staying away from the cloud, this is one of the most frequently mentioned reasons for why they are sticking with their existing solutions. However, even amongst experienced cloud users, security is cited as the biggest challenge. In fact, recent studies highlight that only 23% of organizations completely trust public clouds to keep their data secure. Clearly, security and reliability remain significant concerns when opting for cloud solutions.

The need for visibility

A recent study predicts that the cost of cybercrime will exceed $6 trillion annually by 2021. DDoS attacks continue to be a constant threat with between 131 and 904 attacks taking place per day around the world. Major platforms like the Al Jazeera media website or Skype messanger were already significantly slowed down as result of DDoS attacks this year. Adequate systems that faciliate instant attack detection and visibility are crucial to limiting the harm done by DDoS and keeping networks secure.

Addtionally, this year, leading cloud providers such as Amazon Web Service and Microsoft Azure have already experienced significant cloud outages. The impact of the AWS S3 outage on retailers alone meant that 4 websites were completely down and more than half of the top 100 retail sites experienced significantly slower load times for customers. While firms can’t eliminate this type of cloud failures, they can use strategies and tools to be prepared and limit any resulting problems.

Besides cyberattacks and service outages, network security breaches in popular clouds have been well-documented over the past years. In particular, unauthorized use of cloud applications are posing a serious threat to business IT networks. Latest reports show that IT departments have only 47% visibility into cloud services. Obviously, the less IT is aware of botnets, malware, and Shadow IT, the more the business is exposed to real and potential cyber attacks. Clearly, given the number of threats for network breaches, security and visibility solutions are needed in order to create safe cloud environments.

Network visibility is more than a collection of graphics

Another need for visibility stems from the fact most companies use a multi-cloud strategy and a hybrid cloud approach. 85% of enterprises have a multi-cloud strategy, meaning that they use several different cloud computing services from different providers at the same time within a single heterogeneous architecture. In fact, cloud users are running applications in an average of 1.8 public clouds and 2.3 private clouds. This makes it much more difficult to track and manage data across various systems. Indeed, a recent study shows that the management of multiple cloud services is one of the most important challenges for enterprises these days. Network visibility tools are a great method of dealing with these challenges and understanding what your IT infrastructure looks like, where potential threats may arise and how to proactively manage your multi-cloud environment.
