Next-generation firewalls provide protection but add to workload

Share this article:

A third of organisations have implemented a next-generation firewall to improve protection from attacks.

According to a survey of 130 IT security professionals by AlgoSec, 57 per cent of respondents said that next-generation firewalls seemed to be adding protection but also increase the firewall management workload.

The survey also found that 70 per cent of respondents reported having to make more changes to their next-generation firewalls than traditional firewalls, while 72 per cent suffered an outage or security breach due to an application-related rule change.

Paul Clark, AlgoSec's regional director for UK, Ireland, South Africa & Middle East, said: “Organisations are struggling to manage increasingly complex networks – both from a security and operational perspective. Based on the survey results, it's clear that the biggest challenges for infosec and IT teams come with manual processes and poor visibility, which continue to expose organisations to the risk of outages and security breaches, often caused by their own employees and processes.

“Even those that have adopted next-generation firewalls report that increased security comes at the price of more changes, more policies to manage and more complexity. However, moving away from manual processes and toward automated, centralised management of processes and policies will help organisations to fully realise the potential of next-generation firewalls to improve overall security and reduce costs.”
