Cyxtera announced its agreement to acquire Miami-based offensive-security company Immunity on January 8, 2018. The transaction was completed on June 8, according to Cyxtera’s SEC filing, and the closing was announced publicly on June 11. Cyxtera said the acquisition would add exploit research, penetration testing and attack-simulation capabilities to its defensive threat-management and analytics portfolio. In December 2019, Cyxtera spun off its former cybersecurity business to SIS, so this acquisition should be understood as a historical corporate transaction—not evidence that Immunity products are currently offered by Cyxtera.
When Cyxtera acquired Immunity
| Date | Event | Evidence |
|---|---|---|
| January 8, 2018 | Cyxtera announced a definitive agreement to acquire privately held Immunity, subject to regulatory approvals and customary closing conditions. | Cyxtera announcement |
| June 8, 2018 | The acquisition was completed. | Cyxtera SEC filing |
| June 11, 2018 | Cyxtera publicly announced that the Immunity transaction had closed. | Closing announcement |
| December 2019 | Cyxtera’s former cybersecurity business was spun off to SIS; a separate filing documents the transfer of the business’s outstanding equity interests to SIS Holdings. | Cyxtera SEC filing and reorganization filing |
The two June dates are not contradictory: June 8 is the completion date recorded in the filing, while June 11 is when Cyxtera issued its public closing release.
What Immunity brought to Cyxtera
Immunity, founded in 2002, focused on offense-oriented systems vulnerability research, exploit development and penetration testing. Cyxtera’s announcement described the company as serving Global 2,000 companies and government agencies; that is Cyxtera’s characterization, not an independently audited customer count.
| Capability | How it was described in the announcement |
|---|---|
| CANVAS | Software for security professionals to conduct penetration tests and hostile attack simulations. |
| INNUENDO | Software for modeling data-exfiltration attacks. |
| Testing and assessment | Penetration testing, application assessments and vulnerability analysis. |
| Technical consulting | Reverse engineering, architecture reviews and source-code reviews. |
| Infiltrate | An annual technical conference focused on offensive and counter-offensive security. |
These were software, professional services and an event—not a consumer hardware product. The announcement does not establish current sales, support or ownership of CANVAS, INNUENDO or the listed services.

Why Cyxtera said it wanted the deal
Cyxtera said it intended to incorporate Immunity’s offerings into its threat-management and analytics portfolio. The strategic idea was to pair defensive capabilities—monitoring, analytics and situational awareness—with offensive research and adversary simulation that could expose weaknesses before attackers exploit them. In that framing, the acquisition addressed more of the cyber-attack lifecycle rather than adding another standalone defensive monitoring product.
That was the buyer’s stated rationale, not proof that the integration produced particular customer outcomes. David Aitel, identified in the acquisition announcement as Cyxtera’s chief security technology officer and Immunity’s former CEO, said: “Protecting our customers is going to require both situational awareness and the ability to scale that vision across the complex hybrid computing architectures of the future.”

Cyxtera’s SEC materials say the company spun off the entirety of its former cybersecurity business to SIS in December 2019. The related reorganization filing records the transfer of the outstanding equity interests in that cybersecurity business to SIS Holdings. This later separation is essential context: the 2018 acquisition cannot be used to describe Immunity as a current Cyxtera product line.
The cited filings establish the corporate transfer, but they do not establish the present owner, availability or support status of each Immunity tool or service. Anyone seeking a penetration test or vulnerability assessment should verify the provider, product name and legal entity directly rather than relying on the historical acquisition announcement.

What “Cyxtera acquires Immunity” means in practical terms
- It was an offensive-security capability acquisition: exploit research, attack simulation, penetration testing and related expertise were the central assets described.
- It complemented, rather than replaced, defensive security: Cyxtera presented the combination as offensive assessment alongside threat management and analytics.
- The dates matter: the deal was announced January 8, completed June 8 and publicly announced as closed June 11, 2018.
- It is historical context: the December 2019 spin-off means the deal should not be presented as evidence of a current Cyxtera offering.
