Defence against the dark art of zero-day attacks

Many organisations remain vulnerable to zero-day attacks. Zero-day attacks, by definition, give developers zero time to find and patch existing vulnerabilities that could be exploited, because the threat actor got in first. The damage is done and then it's a mad scramble to fix both the software and reputational damage to the business. Attackers are always at an advantage, and reducing that edge as much as possible is crucial.
