95% of emails is spam
Category : General 26 Jan 2010 09:49 AM | Industry News
A leading European cyber security agency has released its latest ESP spam survey which finds no significant progress has been reported in the fight against spam despite larger anti-spam budgets and management
Less than 5% of email is delivered to inboxes, found ENISA (European Network and Information Security Agency), after surveying ESPs from 27 different European countries together managing around 80 million mailboxes between them.
According to ENISA's Executive Director, Dr Udo Helmbrecht, spam continues to be an "unnecessary, time consuming and costly burden for Europe", adding that "email providers should be better at monitoring spam and identifying the source. Policy-makers and regulatory authorities should clarify the conflicts between spam-filtering, privacy, and obligation to deliver".
ESPs already employ a multiple layers of filtering to reduce spam getting to customers' inboxes. Big money is spent on building and maintaining reputation databases, active blacklists, sender authentication, content filters, source analysis detection and, of course, handling individual complaints from the users themselves. Among very small ESPs, a quarter of respondents allocate anti-spam budgets of over $14,000 per year while around one third of very large providers dedicate anti-spam budgets around $1.4 million per year.
Other findings from the report, which is free to download, include:
  • 70% of respondents consider spam "extremely significant" or "significant" for their security operations.
  • Over 25% of respondents said spam accounted for less than 10% of helpdesk calls.
  • ESPs consider spam prevention as a "competitive advantage" to attract and retain customers. However, spam is not a 'critical factor".
