For over 14 years, A3Sec has operated with a clear mission: to take full responsibility for managing our clients' cybersecurity operations. Today we take a step that strengthens that mission by announcing our collaboration with Andersen Consulting.
This alliance connects our specialized cybersecurity capabilities with the global reach and breadth of professional services of one of the world's largest firms. Here's what this collaboration means for our clients, the market, and the future of A3Sec.
What is Andersen Consulting?
Andersen Consulting is the global professional services firm with a presence in over 1,000 locations worldwide and a team of more than 50,000 professionals. Their network offers consulting, technology, strategy, and transformation services to organizations across every industry. In recent years, Andersen has consolidated accelerated growth with a clear vision: building a network of top-tier specialized firms that work in an integrated manner to deliver comprehensive solutions to their clients.
The addition of cybersecurity capabilities to their ecosystem is not incidental — it responds to the reality that every business strategy today requires robust digital risk management.
What this collaboration means for our clients
In practice, this alliance creates tangible value on three fronts.
First, our current clients gain access to a global ecosystem of complementary services. From legal and tax advisory to strategic and technology consulting, organizations that already trust A3Sec for their cybersecurity can now address additional needs through the Andersen network, with the confidence that their digital protection is managed by a dedicated, specialized team.
Second, organizations working with Andersen network firms anywhere in the world now have access to A3Sec's unified cybersecurity operations services, backed by our Security and Digital Surveillance Center® (CSVD®) operating 24/7 from Spain, Mexico, and Colombia.
Third, our ability to serve multinational organizations requiring consistent, centralized cybersecurity management across multiple jurisdictions is significantly enhanced. For companies operating under diverse regulatory frameworks — from CNBV in Mexico to DORA in Europe — having a partner that understands the local context while maintaining global coordination capabilities is a critical differentiator.
What A3Sec brings to this global network
Andersen Consulting has selected A3Sec as its collaborating firm in cybersecurity based on what we have built over more than 14 years. Our differentiation rests on three pillars.
1. Our proprietary methodology, the A3Sec Method, which integrates prevention, detection, and response services with an operational model driven by data and intelligence. This method is not theoretical — it is what we execute daily for over 280 clients across financial services, telecommunications, energy, and government sectors.
2. Our CSVD®, the Security and Digital Surveillance Center operating from three countries with ISO 27001, ISO 9001, and FIRST certifications, managed by specialized squads that combine automation, advanced analytics, and artificial intelligence. A model we have named the Autonomous SOC: the evolution of traditional security operations toward a model where AI amplifies human detection and response capabilities.
3. And a team of 180+ cybersecurity experts who bring practical experience, not just theoretical knowledge. Every member of our squads operates under a philosophy of continuous improvement and direct commitment to client outcomes.
Why it matters now
The threat landscape is increasingly complex. Organizations face more sophisticated attacks, constantly expanding attack surfaces, and a regulatory environment that demands concrete evidence of risk management.
Recent data shows that cyberattack attempts across the region continue to grow exponentially. In this context, having a cybersecurity partner that is also connected to a global professional services network is not a luxury — it is a strategic necessity. Organizations that understand cybersecurity as a competitive advantage, rather than a cost center, are the ones best prepared to grow in a digital environment.
This collaboration positions A3Sec and its clients precisely in that space: where digital protection moves from reactive to a true business enabler.
What's next
This collaboration marks the beginning of a new chapter for A3Sec. We remain true to our core: a committed team, a proven method, and an operation that never stops. What changes is the scope of what we can achieve.
We will share more details on how this alliance creates tangible value for our clients and the market, including the technology capabilities that underpin our operations and the opportunities opening up in every country where we have a presence.
