Before we start speculating on how bad the bugs are going to get next year, let’s take a look back at some of the worst cyberattacks of 2021.

NaaS soared in 2021; Nvidia touted a new DPU record; and the last 12 months were plagued with vulnerabilities from SolarWinds to Log4j.

“Software has bugs — sometimes severe security bugs, with significant potential consequences,” Forrester analysts wrote.

Cloud security unicorn Wiz says more than 89% of all IT environments have vulnerable Log4j libraries.

Rakuten Symphony extends cost transparency only to its customers; the Log4j vulnerability wreaks havoc; and Rockport ditches switches in HPC environments.

“This vulnerability is so dangerous because of its massive scale,” Forrester Analyst Allie Mellen said.

Other than Aqua, only Palo Alto Networks can secure all components of the application, Aqua CEO Dror Davidoff said.

Analysts are bewildered by Ericsson’s $6.2B acquisition; sponsorship matters for women in cybersecurity; and Red Hat plans to deploy SASE across telecom infrastructure.

The high-severity vulnerability leaves Cisco's FTD and ASA firewall families open to denial-of-service attacks.

“With every Yin, there is a Yang, and while IaC increases agility, any misconfiguration can cause a security risk,” analyst Zeus Kerravala said.

Unit 42 has seen a 188% increase in cloud incident response cases, Palo Alto Networks SVP Wendi Whitmore said.

“In the event when you’re hunting down a threat, it can be a really long, cold winter between discovery and remediation if you lack visibility,” Cisco SVP Al Huger

Positive Technologies disclosed a vulnerability affecting Intel processor families; T-Mobile mid-band 5G covers 200M people; and Ericsson revealed an SMO platform.

The flaw allows an attacker to extract encryption keys from devices running Intel’s Apollo Lake- and Gemini Lake-based Pentium, Celeron, and Atom processors.

Gartner named the top firewall providers; Verizon and AT&T delayed the launch of 5G on C-band spectrum; and AMD released its Milan-X CPUs and Instinct MI200 AI accelerators.

“We offer all our security features baked into the cloud, so we don’t make the customers choose between cost and security,” Oracle VP of Software Bala Chandran said.

Qualys determined that the 36 most prevalent ransomware families used about 110 CVEs. And all of them have patches available for the past several years.

Malware infection rates in North America's fixed networks have also declined throughout the course of 2021 to 2.5%, but still remain well above the low point of 1.1% in

Under the agreement, Siemens will sell its Ruggedcom networking and security platforms with Palo Alto Networks’ VM-Series firewalls built in.

“The market very obviously moved in the direction of OT security. And Dragos has been pretty far out in front of our competitors,” CEO Robert M. Lee said.

Ransomware “is the No. 1 board topic,” CEO Kevin Mandia said during his opening keynote at Mandiant's Cyber Defense Summit event.

Marvell released its first 5-nm switch silicon and DPUS; VMware said it's a critical partner for 5G operators; and AT&T's CSO emphasized the value of effective authentication.

VMware boosted its cloud-native security capabilities at VMworld with a new API security product and posture management services across Kubernetes clusters.

Cisco’s security business only grew 1% compared to a year ago, and that represents much slower growth compared to its competitors like Palo Alto Networks and Fortinet.
