We take a closer look at the cyber giant, XM Cyber, and the areas it specialises its business in...

 XM Cyber is planning to change the way that cybersecurity posture is measured, prioritized and improved. The company's main goal is to bring innovation to the cybersecurity and the security industry with innovative products and services that address the distinctive gaps that arise in large, composite networks. By cautiously and continuously simulating attacks, the company exposes real-life security flaws that arise from vulnerabilities, common human errors and misconfigurations.

The company's innovative system, The XM Cyber Platform, works safely in your live, production environment – it shows you accurate gaps in your security. It also provides you with specific and actionable tasks that are required to fill those gaps based on the potential impact on your company's most critical assets. An example of how the platform can be used is to allow you to find out how a hacker could exploit a certain vulnerability in your company, this can help you plan ahead for a possible cyber attack and create a plan of action for how you would fight against this. 

It has been reported that most cyberattacks occur mainly in cloud-based environments, it is also common that the cyber attacks are caused through error and not vulnerabilities. Many organizations are still adopting cloud services, however, constant changes and new ways of working can create gaps in your cybersecurity, so you always have to develop and be agile. 

As the company continues to grow and branch out its services to other markets, it has picked up numerous awards and received recognition over the years with its latest achievement being crowned the winner of 2020 Black Unicorn Awards. The term "Black Unicorn" means a cybersecurity company that has the potential to reach a $1 billion dollar market value as determined by private or public investment.

Fastly's CDN Reportedly to Blame for Global Internet Outage

Multiple outages have hit social media, government, and news websites across the globe

A huge outage has brought down a number of major websites around the world. Among those affected are gov.uk, Hulu, PayPal, Vimeo, and news outlets such as CNN, The Guardian, The New York Times, BBC, and Financial Times.

It is thought a glitch at Fastly ─ a popular CDN provider ─ is causing the worldwide issue. Fastly has confirmed it’s facing an outage on its status website but fails to specify a reason for the fault ─ only that the problem isn’t limited to a single data centre and, instead, is a “global CDN disruption” that is potentially affecting the company’s global network.

“We’re currently investigating potential impact to performance with our CDN services,” the firm said.

What is Fastly?

Fastly is a content delivery network (CDN) company that helps users view digital content more quickly. The company also provides security, video delivery, and so-called edge computing services. They use strategically distributed, highly performant POPs to help move data and applications closer to users and deliver up-to-date content quickly.

The firm has been proving increasingly popular among leading media websites. After going public on the New York Stock Exchange in 2019, shares rose exponentially in price, but after today’s outages, Fastly’s value has taken a sharp 5.21% fall and are currently trading at US$48.06. 

What are CDNs?

Content delivery networks (CDNs) are a web of small computers, or servers, that link together to collaborate as a single computer. CDNs improve the performance of internet-connected devices by placing these servers as close as possible to the people using those devices in different locations, creating hundreds of points of presence, otherwise known as POPs.

They help minimise delays in loading web page content by reducing the physical distance between the server and the user. This helps users around the world view the same high-quality content without slow loading times. 

Without a CDN, content origin servers must respond to every single end-user request. This results in significant traffic to the origin and subsequent load, thereby increasing the chances for origin failure if the traffic spikes are exceedingly high or if the load is persistent.

The Risk of CDNs

Over time, developers have attempted to protect users from the dangers of overreliance through the implementation of load balancing, DDoS (Denial of Service) protection, web application firewalls, and a myriad of other security features. 

Clearly, by the state of today’s major website outage, these measures aren’t enough. Evidently, CDNs present a risk factor that is widely underestimated ─ which needs to be rectified with haste. Content delivery networks have become a key part of the global infrastructure, and so it’s imperative that organisations start to figure out risk mitigation strategies to protect companies reliant on the interconnected service from further disruption and disarray. 

Over the coming days, both Technology Magazine and Data Centre Magazine will continue to provide updates on the current situation as developments are made.
