Proactive security sounds at first sight like just another marketing gimmick to persuade customers to sign for up for yet another false dawn. After all proactivity is surely just good practice, protecting in advance against threats that are known about, like bolting your back door just in case the burglar comes. To some proactive security is indeed just a rallying call, urging IT managers to protect against known threats, and avoid easily identifiable vulnerabilities. All too often for example desktops are not properly monitored allowing users to unwittingly expose internal networks to threats such as spyware. Similarly remote execution can be made the exception rather than the default, making it harder for hackers to co-opt internal servers for their nefarious ends.
