Cyxtera announced an agreement to acquire cybersecurity firm Immunity on January 8, 2018; the transaction was completed on June 8, with Cyxtera announcing the closing on June 11. The purchase price was not disclosed. The deal added Immunity’s penetration-testing, vulnerability-research and exploit-development expertise to Cyxtera’s broader infrastructure and security portfolio—but the public record describes the strategy more clearly than its later commercial results.
Agreement in January, closing in June
The January announcement concerned a definitive agreement to acquire privately held Immunity Inc., not a transaction already completed. Cyxtera said the deal was expected to close in the first quarter, subject to regulatory approvals and customary conditions. It ultimately closed on June 8, 2018, according to a later SEC filing; Cyxtera’s public closing announcement followed on June 11. Cyxtera’s announcement and its closing announcement confirm the public timeline, while the SEC filing records June 8 as the completion date.
Neither the purchase price nor other financial terms were made public in the cited materials. That means the deal’s valuation, its financial contribution to Cyxtera, and any return on the investment cannot be assessed from the announcement alone.

What Immunity brought to Cyxtera
Founded in 2002 by Dave Aitel, a former National Security Agency analyst, Miami-based Immunity worked in offensive security: authorized testing and research designed to find weaknesses in software, systems and defenses. Its work included vulnerability research, exploit development, penetration testing, vulnerability and application assessments, reverse engineering, architecture reviews and source-code reviews. Cyxtera described customers that included large enterprises, financial organizations and government agencies, and listed offices in Miami, Washington, D.C., and Buenos Aires. The acquisition announcement details the company’s services and products.
#1 Best Overall
Two named tools illustrate the product side of the business:
- CANVAS was a penetration-testing and hostile-attack-simulation tool for security professionals.
- INNUENDO was designed to model data-exfiltration attacks as part of penetration testing.
These offerings sat alongside consulting and research. They were not simply generic “hacking tools”: in professional use, penetration testing and adversary simulation are conducted with authorization to help organizations discover and address weaknesses. But exploit-development expertise and attack tools are dual-use, so the legitimacy of a particular use depends on authorization, controls and purpose.
Why Cyxtera wanted an offensive-security team
Cyxtera was presenting itself as a secure-infrastructure company, combining data-center colocation with cybersecurity and analytics offerings. Its stated rationale was to bring Immunity’s offensive testing and research together with Cyxtera’s infrastructure, customer relationships and defensive security and analytics capabilities. The intended proposition was to help customers test defenses, simulate adversaries and use what those exercises reveal to improve security.
That was a strategic thesis, not proof that the combined services delivered better outcomes. Cyxtera said it planned to integrate Immunity’s capabilities into its threat-analytics portfolio; at closing, it described Immunity’s offerings as incorporated into its threat-management and analytics services. The wording reflects the company’s stated integration, but the cited announcements do not provide post-deal data on product adoption, security results, revenue or customer retention.
At the time of the January 2018 announcement, Cyxtera said it operated 57 data centers and served more than 3,500 enterprise, government and service-provider customers. Those are historical company figures, not current operating statistics. The acquisition followed Cyxtera’s 2017 formation from a CenturyLink data-center business and security and analytics assets associated with Medina Capital and BC Partners. In that context, Immunity was a specialized addition to a broader infrastructure-and-security strategy, rather than evidence that Cyxtera was starting from scratch in cybersecurity.
People and the federal-market rationale
CyberScoop reported that Immunity’s approximately 35 employees were expected to join Cyxtera. Contemporary coverage cited a slightly different headcount, so “about 35” is more precise than treating the figure as exact. Dave Aitel was expected to take a senior technical security role. Cyxtera’s closing announcement identified him as its chief security technology officer and former Immunity CEO. CyberScoop’s report covered the expected team transition and leadership plan.
The deal also aligned with Cyxtera’s federal-market ambitions. The company had recently formed a federal group led by former U.S. Chief Information Security Officer Gregory Touhill. Contemporary reporting described an opportunity to bring Cyxtera’s machine-learning and fraud-detection capabilities to government customers while giving Immunity greater resources and reach. That was an intended market opportunity, not evidence that the acquisition secured particular contracts or deployments. Washington Technology’s coverage provides additional context on the federal strategy.

Immunity also had a place in the technical security community: it had participated in DARPA’s Cyber Fast Track program and operated Infiltrate, an annual conference focused on offensive and counter-offensive security. Aitel said he planned to continue organizing and hosting the conference after joining Cyxtera, according to contemporary coverage.
Best Value
What the public record establishes
The acquisition is a useful example of an infrastructure provider seeking to deepen its security proposition by adding specialist offensive-security talent and tools. The potential benefits were clear in principle: a larger platform could extend the reach of a small research-led company, while penetration testing could complement defensive infrastructure and analytics. The trade-offs are also real. Integrating a small specialist team into a larger business can affect its independence and pace, while dual-use capabilities require appropriate governance. Announcements cannot establish whether those challenges were resolved.
The available cited sources confirm that the transaction closed and describe Cyxtera’s intended integration. They do not establish the purchase price, revenue or profitability, later staffing levels, long-term fate of CANVAS or INNUENDO as standalone products, whether Immunity retained a separate brand, or whether the acquisition produced measurable customer or security outcomes. The clearest conclusion is therefore limited: Cyxtera completed the acquisition in June 2018 to add offensive-security capabilities to its portfolio, but the public announcements do not show how successful that strategy became.
