It's a great product as it helps you to protect your data against different threats. I like that you can customize your own PQ Shield policy, which is great because you have more control of what is included in your protection. It also provides some additional features such as file integrity checks. There are other products with similar functions but they lack the flexibility of PQ Shield. The price is a little bit expensive compared to other products in this category. PQ Shield solves my problem in protecting my data from both internal and external threats. Protecting my data from malicious code attacks.
