Captive portal management has strengthened web filtering and reduced security incidents
Pros and Cons
  • "Squid Proxy Cache Server has positively impacted my organization because I can filter internet access, which protects my company from users accessing malicious sites."
  • "To improve Squid Proxy Cache Server, I believe more marketing and additional training and certification programs are important."

What is our primary use case?

My main use case for Squid Proxy Cache Server is to control internet access and create a captive portal in my last company.

I used Squid Proxy Cache Server to control and filter internet content for all company users and implemented the captive portal for guest visitors.

What is most valuable?

I believe the best features Squid Proxy Cache Server offers are flexibility and customization.

In my case, I needed a tool that provided complete administration and governance, allowing me to configure all options within the application. When I needed to customize Squid Proxy Cache Server for my environment, it was easy to configure, and I used it to set up internet filtering.

I could configure messages for users and restrict access to specific sites as needed. Everything is very straightforward to configure in Squid Proxy Cache Server.

Regarding the captive portal, it is equally easy to configure access duration and time periods for visitor access. The mobile phone interface is very user-friendly. Squid Proxy Cache Server has positively impacted my organization because I can filter internet access, which protects my company from users accessing malicious sites.

It also simplifies providing access to visitors. I installed it on a small server, so the installation requirements are minimal, making it practical to deploy.

I noticed a specific reduction in security incidents after implementing content filtering, as I can now control user access and prevent permission for inappropriate sites. When users click on malicious links, if certain words are in my blacklist, they cannot access that specific site. I remember one instance where a user clicked on a malicious link and could not access the site because Squid Proxy Cache Server blocked it.

What needs improvement?

To improve Squid Proxy Cache Server, I believe more marketing and additional training and certification programs are important.

These improvements would benefit the community and the application.

For how long have I used the solution?

I had the opportunity to use Squid Proxy Cache Server for approximately four years in my last company, Delta Electronics Brazil.

How are customer service and support?

I did not use customer support for Squid Proxy Cache Server because I configured the application myself.

I cannot speak to the quality of support since I did not use it, though I believe good support would be provided if needed.

Which solution did I use previously and why did I switch?

I did not previously use a different solution before Squid Proxy Cache Server.

At that time, I only used Squid Proxy Server.

Which other solutions did I evaluate?

Before choosing Squid Proxy Cache Server, I evaluated several other applications.

I did not prefer them, especially because they required payment and did not have all the features I needed in an application.

I preferred Squid Proxy Cache Server because it was more complete for my requirements.

What other advice do I have?

If I can advise other users about using Squid Proxy Cache Server, I would say it is a good application and tool.

If you have the ability to configure and administer the application, I think it is a good opportunity to use Squid Proxy Cache Server because it is a very effective application.

Regarding Squid Proxy Cache Server's AI capabilities, I believe they are very valuable.

Today, it is impossible not to work with AI, and I think it is important to use AI capabilities to ensure greater security and protection for companies.

Daily access control has boosted staff focus and has improved productivity and security
Pros and Cons
  • "Squid Proxy Cache Server had a positive impact on my organization by being the main factor helping with productivity."
  • "In my opinion, Squid Proxy Cache Server can be improved by covering more issues, having more updates, and providing a slightly more updated version of lists and logs and information that we can distribute to other places for a more complete monitoring of it."

What is our primary use case?

I have been working in my field for more than 15 years. I used Squid Proxy Cache Server for approximately 5 to 7 years, though I am not using it lately. My main use case for Squid Proxy Cache Server was when I used pfSense, and it was very important for me to have Squid Proxy configured. I mainly used it for website blocking to provide full security coverage, particularly focusing on the matter of accesses and analysis of different clients within the company, and I used it daily within a scenario together with pfSense.

How has it helped my organization?

Squid Proxy Cache Server had a positive impact on my organization by being the main factor helping with productivity. By doing this control and handling the quality of accesses, the quality and performance of the staff got much better.

What is most valuable?

I think the best features that Squid Proxy Cache Server offers are the block list via ACL, which helps a lot, the basic installation with pfSense that I used frequently, and the interesting log records, which are very helpful for us. The features such as the block list via ACL and log recording made our work easier by helping to ensure that employees had better quality of performance in terms of blocking, so people stay more focused and more engaged in what they have to do and do not get distracted with sites or networks they should not be accessing.

What needs improvement?

In my opinion, Squid Proxy Cache Server can be improved by covering more issues, having more updates, and providing a slightly more updated version of lists and logs and information that we can distribute to other places for a more complete monitoring of it.

For how long have I used the solution?

I have been working in my field for more than 15 years.

What do I think about the stability of the solution?

Squid Proxy Cache Server is stable in my experience.

What do I think about the scalability of the solution?

In my opinion, the scalability of Squid Proxy Cache Server is very good.

Which solution did I use previously and why did I switch?

I did not previously use a different solution before Squid Proxy Cache Server.

How was the initial setup?

When I chose Squid Proxy Cache Server, I did not evaluate other options because it came up first during my research, and I already had the integration, which made it much easier to use.

What about the implementation team?

At the time when I used Squid Proxy Cache Server, it was implemented on a local network, on a machine that had several Docker containers, and inside it, there was pfSense which handled all the ACL control along with Squid Proxy Cache Server.

What was our ROI?

I did not observe any practical result in terms of monetary values after implementing Squid Proxy Cache Server because I always used it as open source, together with pfSense, which is also open source. Everything was configured manually, and I did not have much improvement in terms of cost because there were none.

What other advice do I have?

I think the best features that Squid Proxy Cache Server offers are the block list via ACL, which helps a lot, the basic installation with pfSense that I used frequently, and the interesting log records, which are very helpful for us. My advice to other people thinking about using Squid Proxy Cache Server is that you can use it because it is worth it. I would rate this product a 10 out of 10.

Caching has reduced bandwidth usage and now improves access control for secure web traffic
Pros and Cons
  • "The best features Squid Proxy Cache Server offers include its storing mechanism and the ability to handle a wider range of protocols, which significantly reduces latency."
  • "In terms of how Squid Proxy Cache Server can be improved, I believe that a few more details regarding how information is stored in the request-response cycle can be enhanced, especially in hit scenarios, and a few of the security architecture tools can also be improved."

What is our primary use case?

My main use case for Squid Proxy Cache Server is caching purposes when an enterprise architecture is implemented, and I ensure that the proxy server is used whenever there is HTTPS traffic.

For a full-fledged client and server architecture, whenever there is an internal requirement to reduce bandwidth, I use the caching mechanism of Squid Proxy Cache Server. Since it is an open-source tool, it has full features and sits between my clients, ensuring that whatever is frequently called is managed efficiently.

What is most valuable?

The best features Squid Proxy Cache Server offers include its storing mechanism and the ability to handle a wider range of protocols, which significantly reduces latency.

In my daily operations, Squid Proxy Cache Server's storing factor and latency reduction stand out because it is straightforward. Whenever there is a caching requirement, the web objects are stored locally, and when I refresh the page, the proxy server fetches them and sends them to the user making that request. This reduces the internal request time for local usage as well as future requests, making it much more efficient.

Squid Proxy Cache Server includes an access control list and login features, which is a handy feature. Squid Proxy Cache Server has positively impacted my organization by providing me with the access control list and login features, and it acts as a forward proxy, although it is majorly used as a reverse proxy accelerator for inbound traffic.

What needs improvement?

In terms of how Squid Proxy Cache Server can be improved, I believe that a few more details regarding how information is stored in the request-response cycle can be enhanced, especially in hit scenarios, and a few of the security architecture tools can also be improved.

Regarding improvements needed for Squid Proxy Cache Server, since it is an open-source tool, I think that security, logging, and architecture are fine; however, the reverse proxy accelerator can be improved to better monitor inbound traffic for zero-day attacks that need to be transferred and enhanced.

For how long have I used the solution?

I have been using Squid Proxy Cache Server for almost eight years.

What other advice do I have?

I have no particular advice to give to others looking into using Squid Proxy Cache Server. I find this interview process valuable. I gave this review a rating of 8.

Which deployment model are you using for this solution?

Hybrid Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
