How do ISPs help reduce the risk of phishing?

ISPs (Internet Service Providers) play a critical role in enhancing online security, particularly in combating phishing threats. When ISPs filter out phishing emails, they help protect users from malicious attempts aimed at stealing sensitive information such as usernames, passwords, and financial data. This filtering is achieved through various techniques, including the identification of known phishing websites and suspicious email characteristics, which enables the ISP to block or quarantine potentially harmful content before it reaches the end user. By implementing such measures, ISPs create a safer internet environment that minimizes the likelihood of users falling victim to phishing attacks.

The other choices do not directly contribute to reducing the risk of phishing. Increasing internet speed can improve user experience but does little to address security threats. Providing free antivirus software may offer some protection against malware but does not specifically target phishing emails. Restricting access to social media can limit exposure to phishing attempts that often occur on these platforms, but it does not effectively prevent phishing via email, which remains a predominant method of attack.
