Elastic vs Splunk H1B Sponsorship: 2025 Search & SIEM Guide
Elastic and Splunk are the two leading platforms for log analytics, observability, and SIEM (Security Information and Event Management). Elastic remains an independent public company (NYSE: ESTC); Splunk was acquired by Cisco in March 2024 for $28 billion. Both continue to sponsor H1B for software engineers, data engineers, and security engineers, though Splunk's program is now managed under Cisco's immigration infrastructure.

Elastic H1B Sponsorship
Elastic is the company behind the Elasticsearch open-source search and analytics engine, which powers billions of searches daily across e-commerce, observability, and security use cases. The company sponsors approximately 200+ H1B applications annually for software engineers, ML engineers, and data engineers. Elastic pays a median H1B base salary of $165,000. Elastic operates a distributed-remote-first culture, providing more flexibility than most H1B-sponsoring companies. Key products include the Elastic Stack (ELK), Elastic Security (SIEM), and Elastic Observability. Vector search for AI applications is a major growth initiative.
Splunk (Cisco) H1B Sponsorship
Splunk, acquired by Cisco in March 2024 for $28 billion, is the market leader in enterprise SIEM and IT operations analytics. Prior to the acquisition, Splunk filed approximately 350+ H1B applications annually. Post-acquisition, Splunk H1B petitions are now filed under Cisco Systems Inc., providing access to Cisco's significantly larger immigration infrastructure and PERM program. Median H1B base salary is $168,000 — comparable to pre-acquisition levels. Cisco's acquisition provides Splunk employees with more stable employment and better green card program resources, though Splunk's culture and product roadmap have been integrated into Cisco's security and networking portfolio.
Verdict
Splunk (now Cisco) pays marginally more and has access to Cisco's larger immigration and PERM infrastructure following the acquisition. Elastic offers better remote work culture, independence, and exposure to open-source technologies like Elasticsearch that are widely used beyond Elastic itself. For H1B candidates prioritizing employment stability and green card PERM resources, Cisco/Splunk is the stronger choice. For those valuing open-source culture, remote flexibility, and vector search/AI infrastructure work, Elastic is an excellent option.
Frequently Asked Questions
How do Elastic and Splunk H1B salaries compare?
Splunk/Cisco pays a median H1B base salary of approximately $168,000 versus Elastic's $165,000. The difference is minimal — approximately 2%. At senior engineering levels, both companies pay $185,000–$220,000 in base. Cisco's acquisition of Splunk has not materially changed Splunk's compensation levels.
How does the Cisco acquisition of Splunk affect H1B sponsorship?
The Cisco acquisition in March 2024 means Splunk employees are now legal employees of Cisco Systems, Inc. This is beneficial for H1B: Cisco is one of the largest H1B sponsors in the US (4,000+ annual filings) and has very mature immigration infrastructure. Splunk H1B transfers now benefit from Cisco's larger legal and HR organization, which typically means faster PERM processing and more robust immigration support.
How transferable are Elasticsearch skills compared to Splunk SPL skills?
Elasticsearch/ELK skills are more broadly transferable than Splunk SPL (Search Processing Language). Elasticsearch is an open-source technology used by thousands of companies independently of Elastic. Splunk SPL is proprietary to Splunk. Engineers with Elasticsearch expertise can work at companies using self-managed Elasticsearch, OpenSearch (Amazon's fork), or Elastic Cloud. Splunk SPL expertise is primarily valuable at companies using Splunk Enterprise or Splunk Cloud.
How does remote work compare at Elastic vs Splunk?
Elastic operates as a distributed-remote-first company, offering significant flexibility. Most Elastic H1B employees are not required to be in a specific office. Splunk, now part of Cisco, follows Cisco's hybrid work model (approximately 3 days per week in-office for most roles). For H1B candidates who value location flexibility, Elastic's remote-first model is a material advantage.
What is the SIEM market outlook for H1B security engineers?
SIEM is a $5B+ market growing at approximately 14% annually through 2028. Cloud SIEM adoption is accelerating as enterprises move from on-premise Splunk to cloud-native solutions. Both Elastic Security and Splunk Cloud are competing for cloud SIEM market share. Security engineers with SIEM, threat hunting, and SOAR (Security Orchestration, Automation, and Response) skills are in high demand at both companies and across the broader cybersecurity market.
