Survey Uncovers High Level of Concern Over Firewalls
More than half of respondents are planning to reduce their network firewall footprint because of what they see as limitations in the technology.

A relatively high percentage of cybersecurity leaders apparently perceive most firewall technologies — long a linchpin of enterprise security — as being ineffective in protecting their applications against attack.


The Ponemon Institute recently surveyed 603 US security professionals on their firewall use. The survey, sponsored by Guardicore, asked respondents to evaluate the effectiveness of firewalls in blocking ransomware and a range of other existing and emerging threats.


For purposes of the research, Ponemon defined legacy firewalls as including network appliances, virtual firewalls, and so-called next-generation firewall technologies. The survey encompassed both "stateful" firewalls that inspect incoming and outgoing network traffic and firewalls that integrate threat intelligence, intrusion prevention, application access control, and other features.


The results reveal that organizations are highly unhappy with their current firewall technologies. More than half (53%) of the respondents say they're either moving away from or reducing their dependence on firewalls and looking at other options.


Six in 10 of the security leaders in the survey believe legacy firewalls don't have the capabilities to protect critical application and systems from attack. An identical 60% describe legacy firewalls as being of little help in enabling a zero-trust environment, and 76% say it took them too much time to secure new applications or to change configurations with their legacy firewalls.


"The biggest complaints we're hearing from organizations on legacy firewalls is that they kill speed and flexibility and are not providing the required needs around security," says Dave Burton, vice president of product marketing at Guardicore.


According to Burton, 57% of respondents say they sometimes take as much ..
