Standalone security software is designed for people who have more knowledge on how to protect their system against most threats and wish to use particular tools to combat particular threats. As we know already, there are several types of risks: malware, spam, intrusion, vulnerability, exploits, potentially unwanted software (PUPs), rogue or misleading applications, phishing, fake or malicious websites etc.
The main advantage of using standalone products is that you can choose the products that you think will provide your computer with the best protection against each threat rather than relying on a single vendor. For example, while most security suites now offer some form of parental controls, those controls will probably not be as comprehensive as the ones found in a dedicated, standalone product such as Net Nanny.
Examples of standalone tools include:
This main disadvantage of standalone products is that they can be time consuming. Simply deciding which products to use can be a challenge. And you then have to install them, learn how to use them, make sure that they work well together and keep them all updated.
