What it is

BGP Hijacking happens when internet traffic is wrongly redirected through another network, either by mistake or on purpose.

Why it matters

Traffic meant for your website or service could be intercepted, monitored, or disrupted without touching your servers.

How to reduce risk

  • Use routing security protections where possible
  • Monitor changes affecting your network routes
  • Work with trusted internet providers
