1) You have to patch servers irregardless of whether they are protected by other mechanisms or not. You're still vulnerable to an internal attack on sendmail, which Sidewinder would do nothing about. <pet peeve>Security doesn't start and end at the edge. Blaster/Nachi should have skewered that canard forever. So why do vendors still advertise as if it does?</pet peeve> 2) There are other methods of protecting yourself, such as using mail servers that aren't made of swiss cheese like sendmail is. 3) What happens when Sidewinder fails? Does it fail open? If it does (and it should), is their version of sendmail still protected? Or is it sitting on the Internet bare-ass naked, waiting to be 0wn3d? 4) I'm a big believer in not clumping all your services in one place. Single points of failure shouldn't result in complete disaster to an organization. At least not those parts that you can control. 5) If a vulnerability to sendmail was discovered that Sidewinder couldn't protect against, you're at the complete mercy of Sidewinder to provide a fix. In the meantime, you're screwed. 6) I don't think highly of security companies that use known insecure solutions. They could have chosen Postfix or Qmail. Yet they chose sendmail and "hardened" it. Makes me wonder about their powers of judgment.
