Denial of Service Protection

Protect, monitor and defend

Have the confidence to manage unwanted attacks against your websites in Australia and overseas with our Denial of Service Protection solution.


Help your business stay online

Protect your organisation from internet attacks known as Distributed Denial of Service (DDoS) - which can deliberately cause downtime to internet services and impact productivity, customer trust and satisfaction, and cause financial loss.

Organizations operate in a digital world where cyber security threats are becoming more sophisticated. In particular, distributed denial of service, or DDoS attacks, are one of the most prevalent threats to business today.

According to NetScout’s latest threat intelligence report, 5.4 million DDoS attacks were launched in the first half of 2021, an 11% increase over the same period the year before, with both the size speed and sophistication of attacks also increasing. The expectation is that 2021 will be a record-breaking year for all the wrong reasons, threatening organizations large and small across multiple industries.

So what is a DDoS attack? In a nutshell, DDoS attacks are designed to take your business offline. Using compromised computers or servers across the internet, attackers send an overwhelming volume of traffic towards a target, and if it happens to be your website or server it's a problem. As your server is flooded with traffic, it grinds to a halt. Your customers and partners can't get a foot in the door. What they'll see is a slow or unresponsive website. This is denial of service. DDoS attacks can be part of an extortion threat, or politically motivated. Perhaps it's just for annoyance, or vandalism. Whatever the motivation, when your website is closed for business, it can result in significant reputational and financial damage. That's where Telstra DDoS can help.

Telstra Denial of Service Protection gives you the confidence to help manage DDoS attacks targeting your critical online assets and websites. Using DDoS threat intelligence and automation, when a DDoS attack is detected, our security operations centre will quickly assess the threat. They'll then contact you to discuss the threat and its potential impact and make a decision in consultation with you to begin mitigating the attack.

Depending on a pre-agreed plan you'll also have the option for mitigation to happen automatically. Telstra then directs the traffic to one of our global cleaning centres, surgically removing the attack traffic and delivering legitimate traffic to where it's supposed to go. The result, your business can stay online, and the attack is neutralized.


Why Telstra?

Telstra’s denial of service protection has been built with 24/7 global protection in mind. A key feature of Telstra’s DDoS solution is the global presence of these cleaning centres, which allow the DDoS platform to help mitigate a DDoS attack closer to its source. Locally, DDoS alerts are monitored 24/7 by a dedicated team of cyber security analysts within our t4 certified security operations centres based in Australia. And there's no need to purchase, deploy, or install any additional hardware. Also, no need to hire specialist security staff, Telstra DDoS fills those gaps, in fact, Telstra has been protecting customers in high-risk sectors from DDoS attacks including finance, and state and federal government for more than a decade.
