Introduction
HashiCorp Vault has long been known for its robust security automation, particularly in secret management for enterprises. However, with increasing demand for scalability and performance, the release of HashiCorp Vault 1.18 brings key updates that cater to large enterprises. These updates focus on improving speed and reliability through changes to the Raft database, adaptive overload protection, and a gradual push towards cloud integration. Let’s explore how these updates target scalability while maintaining security standards.
HashiCorp Vault 1.18: Enhancing Scalability for Large Enterprises
HashiCorp Vault version 1.18 introduces significant enhancements to meet the needs of large-scale enterprises. Among the most critical updates are the improvements to the Raft database, which serve to enhance Vault’s performance in high-traffic environments.
Updates to the Raft Database
The Raft database update focuses on improving the reliability and speed of Vault’s performance, particularly in failure mode. Traditionally, Vault’s use of Raft to manage a cluster of servers could result in short disruptions during the election of a new leader server. For smaller clusters, this was not a significant issue, but for large enterprises handling thousands of requests per second, even a few seconds of downtime could cause major disruptions.
According to Armon Dadgar, HashiCorp co-founder and CTO, the new update minimizes such disruptions by ensuring that network partitions no longer cause significant connectivity blips. This improvement is crucial for companies handling high volumes of sensitive data, such as SAP Concur, which relies on Vault to manage PKI certificates, secrets, and database credentials.
Adaptive Overload Protection for High-Volume Environments
Another key feature in Vault 1.18 is adaptive overload protection. This update allows Vault to dynamically manage the number of concurrent requests based on available system resources. By queuing requests that exceed system capacity, Vault can handle overloads more gracefully without slowing down or crashing.
For enterprises like SAP Concur, which signs over 2,000 PKI certificates and retrieves 8,000 secrets every hour, adaptive overload protection is essential. As Dale Ragan, a software design engineer at SAP Concur, points out, their team faced challenges with engineers unintentionally creating denial-of-service (DDoS) situations by overwhelming Vault. Adaptive overload protection resolves this issue, making the system more scalable and reliable.
HCP Vault Radar: Strengthening Security in Cloud Environments
Alongside Vault 1.18, HashiCorp also introduced the public beta of HCP Vault Radar, a secrets scanning utility designed to prevent sensitive information from being exposed during the development process. Vault Radar integrates with code repositories and CI/CD pipelines, allowing it to scan for secrets in code commits, pull requests, and more.
Secrets Scanning and Code Repository Integration
Vault Radar’s ability to detect exposed secrets early in the development process is a significant advantage for enterprises, particularly those with stringent security requirements. The tool provides Vault secret correlation, meaning it verifies whether a secret found in a scan is valid and offers remediation guides for any secrets exposed.
For organizations like LPL Financial, the ability to scan for exposed secrets at the beginning of development is critical. LPL Financial also uses Prisma Cloud’s security scanning tool during the CI/CD process, but Vault Radar provides additional value by scanning Terraform modules when they are first created, reducing the risk of security misconfigurations down the line.
Adoption by Enterprise Clients Like Adobe
Adobe is one of the large enterprises considering Vault Radar. Tyler Jacobsen, Director of Cloud Operations and Engineering at Adobe, acknowledges that the scanning capabilities of Vault Radar, combined with its on-premises agents, help reduce concerns about sensitive data leaving the company’s environment. This architectural decision lowers the barrier to adoption, enabling organizations to start using Vault Radar without exposing confidential information to the cloud.
HashiCorp’s Cloud Push with Vault: A Slow Yet Steady Transition
While HashiCorp has been cautious about pushing Vault users into the cloud, the latest updates signal a gradual shift. Vault Radar’s support for on-premises agents offers large enterprises a bridge to the cloud, allowing them to manage security with greater flexibility.
Vault Radar’s On-Premises Agent Support
By offering support for self-managed agents in Vault Radar, HashiCorp provides a solution for enterprises that are not ready to fully commit to the cloud. This feature allows companies to benefit from Vault’s secrets management capabilities while maintaining control over their most sensitive data. As Adobe’s Jacobsen noted, keeping the “crown jewels” in-house is a priority for many enterprises.
Future Cloud Migration Challenges and Opportunities
Despite this slow approach, the pending IBM acquisition is expected to accelerate HashiCorp’s move towards cloud services. Justin Lam, an analyst at 451 Research, believes that post-acquisition, HashiCorp will shift to a more cloud-centric model, offering greater revenue potential through SaaS offerings.
Large enterprises may soon face decisions regarding whether to move their secrets management to the cloud. However, given Vault’s essential role in the security infrastructure of organizations, many will likely opt for a hybrid approach, balancing on-premises security with cloud-based scalability and convenience.
Conclusion
HashiCorp Vault’s 1.18 update, along with the introduction of HCP Vault Radar, marks a significant step forward in scalability and security for large enterprises. By addressing the needs of high-volume environments and offering flexible cloud migration options, HashiCorp is positioning itself as a leader in enterprise-grade security solutions. As the company prepares for its acquisition by IBM, the future of Vault’s scalability and cloud integration looks promising for both new and existing customers.
