Australia’s Oldest Law Firm Invests in Human Layer Security

Saturday, September 28th, 2019

Tessian Cloud Email Security intelligently prevents advanced email threats and protects against data loss, to strengthen email security and build smarter security cultures in modern enterprises.

Allens is one of Australia’s leading commercial law firms with offices throughout Australia and 28 international locations through a global alliance with Linklaters. For almost 200 years, Allens has prided itself on providing excellent client service. The firm has worked with many of the world’s leading organizations both within Australia and abroad.

Allens is protecting 1,100 employees with Tessian DefenderTessian Guardian, and Tessian Enforcer. 

“Data security is a key pillar for our IT strategy and something we take seriously at the firm.”
Bill Tanner Chief Information Officer

Looking for better data security oversight

Allens is the oldest law firm in Australia, and has a proud heritage of supporting its clients through important matters. Bill Tanner is the Chief Information Officer at Allens and looks after endto-end IT delivery for the firm across Australia and South East Asian territories. Law firms like Allens receive sensitive company and client data on a daily basis. For Bill, ensuring the firm’s technical stack remains up to date and secure is a top priority. As Bill says, “Allens wants to help our people identify potential threats but also ensure our people don’t inadvertently expose our systems.” Searching for a solution that could simultaneously protect their people from security threats, while building awareness within the workforce as to how threats manifest on email, Allens turned to Tessian.

“Tessian’s ability to seamlessly secure against human-centered risks on email with minimal disruption has helped minimize the possibility of data breaches.”
Bill Tanner Chief Information Officer

Mitigating inbound and outbound threats

Tessian’s Guardian, Enforcer and Defender filters were seamlessly integrated into Allens’ security stack. After deployment, Bill and his team were able to immediately see the filters’ success in eliminating threats from both inbound and outbound emails. The high accuracy of the Tessian platform meant employees could still be protected while continuing their day to day business without interruption.

Mail being sent to the firm has increased 57% over the past six months. Whilst there has been a 74% increase in the volume of mail rejections, this correlated with an 8% improvement in rejection rate. Mail-based attacks continue to rise, and attackers are getting more sophisticated with their techniques. Allens was looking to bolster its existing defences by providing additional context around the potential threats landing in employees’ inboxes.

Tessian’s Defender module detects anomalous incoming emails in real time, delivering warnings to employees that both prevent the attack having any impact and educate them as to why the email looks suspicious. To Bill, Defender’s intelligent notifications “provide that context in the moment that is so important for our people.”

“The whole firm has to be confident we have the right systems and the right tools to support our people. They need to know we’re doing everything we can to protect the organization.”
Bill Tanner Chief Information Officer

Creating a conscious security culture

As data security threats continue to threaten the legal sector, it will be vital for firms like Allens to invest in cutting-edge technology to mitigate the risk of data loss and spear phishing attacks, and the potentially disastrous repercussions of data breaches. With Tessian’s filters protecting Allens employees in multiple territories, Allens has increased the protection of the sensitive data held by the firm as it continues to deliver the high standard of service the firm has provided for almost 200 years.
