Prevent Phishing Attacks with Proactive Web Filtering Services



Phishing attacks are the security bane of companies of all sizes, in all industries. A seemingly innocuous email can actually be a spoofed message sent by increasingly sophisticated hackers seeking to infiltrate your network via a simple click.

These “social engineering” scams are effective because they take advantage of our tendency to “click first, think later”, especially if we believe the source of the link to be from a trusted source. Financial advisors should consider a multi-faceted approach to confronting Phishing attacks -- continuous employee awareness training, anti-Phishing plugins / toolbars, etc.

Another very effective Cybersecurity measure is to implement Cisco Umbrella (formerly known as OpenDNS) -- effectively an internet filter that restricts clicks/links from launching malicious websites, thereby preventing viruses or malware from locking up your system or exposing confidential client data to hackers.

Deploying Umbrella is a cost-effective solution, but requires optimization and best deployment methodology for maximum effectiveness. Contact RSI for a free, no obligation consultation on how Umbrella can be implemented for proactive phishing protection.

Web Filtering Types

There are several options when it comes to web filtering tools, and different types will work better in different environments. Common types of web filters include:

  • Browser-based filters
  • Network-based filters
  • Content-limited ISPs
  • Client-based filters

Choosing the right type depends on the policies or regulations that need to be adhered to and how scalable the solution needs to be.

Why Web Filtering is Important

Internet safety is a genuine concern for many reasons. Activity monitoring and web filtering can help enforce cybersecurity policies, prevent incidents and keep systems and data secure.

And since web filtering can prevent both malicious and inappropriate content from being accessed, it can contribute to building both a more secure and more productive environment.

How Web Filtering Works

Web filters all work by filtering out specific content, but different types of filters achieve this in different ways. For example:

  • Content-based and keyword-based filtering These approaches filter out websites based on specified content or keywords.
  • Blacklists Also known as "block lists," these filters allow the administrator to define a list of specific websites to block, allowing all others.
  • Whitelists Also known as "allow lists," administrators can use these to specify which sites to allow access to, blocking all others.
  • DNS filtering DNS filtering, also known as OpenDNS filtering, makes use of existing blacklists and whitelists of known malicious or safe web content to filter what can be accessed.

Web Filtering FAQs

Web filters prevent users from accessing certain kinds of content on the web. How this is done and what gets filtered depends on the type of filter being used and how it is configured.

Choosing between web filtering solutions requires consideration of how the users of your network are accessing online content, what they need access to, and what content could present risks or is otherwise undesirable. Industry is also a factor; the best security tools in e-commerce will be different than the best ones for a community service organization.

It also depends on your organization's IT environment and infrastructure.

RSI's team of security experts will evaluate your organization's environment and security needs to determine the best web filtering strategy to keep your networks safe from malicious content.

Web filtering and firewalls are two different things, but both can be used to help keep your networks more secure. Web filters are used specifically to block web content while firewalls are used to prevent unauthorized network access. Neither can replace the other, and the best solution will likely utilize both.

The Internet makes every system more vulnerable to threats. Web filters improve computer security by reducing exposure to potentially malicious content. Web filtering can be used to block known malicious websites and suspicious content, reducing the risk of computers becoming infected or breached.
