What are the benefits of a Phishing Testing Service?

Humans have always been the weakest link. That’s a fact. A phishing simulation stress-tests your human firewall, which is often your final and only defence. Cyber criminals are relying less on complex hacking and instead bypass your security entirely by targeting your employees. All it takes is one team member to hand over the keys. That’s why proactive workforce training is invaluable to your business.

Common Phishing Challenges

Staff Awareness
Some workforces may not have dedicated cyber awareness training in their induction. Staff may be uninformed about how to detect such scams and often unaware of the risks of clicking suspicious links. 
Sophisticated Phishing Methods
Phishing is commonly known as an email attack, but cyber criminals use many other modern methods to exploit people and organisations. Examples include vishing (voice phishing), quishing (QR code phishing), smishing (SMS scams), and whaling (high-profile attacks aimed at CEOs and CFOs).
Personalised Attacks
Spear phishing is a highly targeted, often personalised attack aimed at a single person within an organisation. Attackers tailor these campaigns to look as convincing as possible by mimicking real personal and company details.

Frequently Asked Questions: Phishing Testing Service

Take a look at our frequently asked questions and find the answers you’re looking for. Our FAQ provides clear and concise responses to common inquiries.
What is Social Engineering?

Social engineering is a psychological technique used to manipulate people into breaking security protocols, sharing sensitive information such as passwords, or sending money. Phishing is a type of social engineering; however, social engineering is a broader term that often branches into physical security.

What are the 4 P’s of Phishing?

Pretend – Attackers pretend to be an official or trusted person, such as your IT provider. 
Problem – Inventing a fake crisis with a sense of urgency to cause distress, fear, or worry. 
Pressure – Applying pressure to make you act fast without thinking, using potential threats and time limits to heighten the urgency. 
Pay – The final goal is to get you to ‘pay ’, not necessarily with money, but by handing over passwords, clicking links that open malicious software, or sharing personal data.
