His team protects email, core IT and child welfare data, among others. Cyber resilience means not relying on a single resource for backups, he says, but combining backup and recovery with virtualization, storage snapshots and replication.
“Whether it’s internal or external, inside or outside, whether it's malware, ransomware or AI-driven, there are so many possibilities that if we're trying to provide one solution to fit the bill for everything, we are missing a mark on what we really need to be doing,” McCarthy says.
Cohesity saves the state money by offering multiple capabilities in one platform, including compute, storage and backup.
“We've made a large investment in our people and training and putting in the best solutions we can to be cyber resilient and protect our data from these types of incidents, while also having multiple routes and possibilities to react in those cases,” McCarthy says. “Because none of these situations are ever orchestrated the same way.”
Pursuing Immutable Backup
For New Orleans CIO Kim Walker LaGrue, cyber resilience means the city can maintain continuity of services for its citizens, whether it’s recovering from a cyberattack or a hurricane.
“For any type of interruption, cyber resilience means that the city continues to deliver those services in the most critical situations and in the most routine situations,” LaGrue says. “Whether it is information about crime or geospatial data about where events are happening in the city, that type of information is critically important to delivering city services effectively.”
In December 2019, New Orleans suffered a ransomware attack, and all technology services went offline. The city did not pay the ransom.
“We understood the imminent threat to the city's environment,” LaGrue says. “We had made that decision and really braced ourselves for an attack, had a good backup strategy and made sure that we were regularly backing up our data.”

The New Orleans IT team had to disconnect all systems from the internet, so all city technology operations were shut down.
“We were looking to migrate to something that would allow us to simplify our storage environment, remove some of the complexities and introduced flash storage in a more cost-effective manner,” LaGrue says. “We wanted to get more value for what we were paying at the time.”
To recover from the cyberattack, New Orleans assessed the data it had at rest, inspected it and moved it to clean storage. Next, it brought the backups online. Three or four days after the attack, the city signed up with Pure Storage to gain faster storage and immutable backups.
New Orleans also integrates backup and recovery tools from multiple vendors. Veeam worked with Pure Storage as a complete solution to help the city bring services back online after the ransomware attack. During this process, setting up immutable backups and a secondary data center were key.
“Pure Storage also allowed us to set up replication in our offsite data center, which gave us a better opportunity to recover quickly, should we face another disaster or unexpected interruption to our business. That, along with immutable backups, let us begin a recovery process and feel comfortable about the backup strategy that we had,” LaGrue says.
