Expertise & Solutions
Network, cybersecurity, cloud and AI: integrated expertise
Security is never decided by a single product. It rests on the coherence between your network, your access controls, your cloud and your practices. We work across all four at once.
Network & connectivity
Architectures built for performance, availability and growth.
Most of the networks we take over were never designed : they grew. A switch added for an office move, a VLAN created for one project, a carrier link renewed by default. Fifteen years later, nobody in the organization knows which flows actually cross the core. An attacker finds out in an hour.
So our work starts by mapping the real traffic, not by reading the official architecture diagram. We then design the target architecture (LAN, MAN, WAN, SD-Access, high-density Wi-Fi)and migrate in reversible waves: every cutover has its window, its validation criteria and a tested rollback plan. It is slower than a single overnight switch. It is also why our multi-site migrations do not interrupt service.
40+ sites migrated in 9 months for a public body, with no interruption to citizen services.
Cybersecurity
Protect critical assets with proven Zero Trust architectures.
Segmenting a live network means accepting that something will break. The real question is not how to avoid it, but what, when, and how to roll back. That is why so many Zero Trust projects stall right after the audit: the mapping is done, the report is written, and nobody dares to cut over.
We therefore treat segmentation as an operations project, not a security project. Passive flow discovery, trust zones defined together with your application teams, observation mode before enforcement mode, then zone-by-zone cutover with a rollback window at every step. SASE, network access control and identity management follow the same rule: no policy is enforced before it has been observed causing no side effects.

Cloud & modernization
Migrate, secure and monitor your hybrid environments.
Cloud migrations rarely fail for technical reasons. They fail because three decisions were never made up front: where the data lives and under which law, what stays on premises and why, and who operates it after the cutover. Without those answers, the organization inherits a hybrid architecture it endures rather than chose, and a bill that drifts month after month.
We settle those three decisions before any Azure or AWS migration, with Law 25 constraints on the table at scoping rather than discovered at the end. Then comes the engineering: hybrid networking, identity, logging, backups, and FinOps discipline from month one : cost optimization is designed in, not retrofitted. We resell no licences, which makes our architecture trade-offs verifiable.
Architecture team certified on Azure and AWS, and no licence resale: our recommendations carry no hidden commercial interest.
Automation & AI
More resilient, performant and predictable infrastructure.
On critical infrastructure the problem is not a shortage of alerts : it is thousands of them a day. Teams end up ignoring them, and incidents get reported by users before monitoring catches them. Adding one more tool does not change that mechanism.
So we work on the signal-to-noise ratio: automated event correlation, thresholds learned from the network's actual behaviour rather than set by hand, dashboards organized by service rather than by device. Automated remediation exists, but within a scope agreed with you and fully logged : trigger, rule, outcome. Anything outside that scope requires human validation: in the sectors we serve, auditability is not negotiable.
35% fewer incidents in one year on a banking infrastructure, with detection ahead of user impact.

Network, cybersecurity and cloud: integrated expertise
An organization's security is never decided by a single product: it depends on the coherence between its network, its access controls, its cloud and its practices. RISS Canada works across all four at once: we audit what exists, design the target architecture, deploy it without service interruption, then operate it or hand it to your teams.
Our consultants are certified on the technologies we deploy (Cisco, Fortinet, Palo Alto, Microsoft Azure, AWS) and work in environments where downtime is not an option: banking network cores, multi-site public-sector networks, converged industrial OT/IT environments.
Every engagement is documented, tested and auditable. That is what keeps a regulatory audit, an incident recovery or a change of staff from undoing your security posture.
Key points
- Four domains handled together: network, cybersecurity, cloud, automation and AI.
- Most of our engagements are on existing production environments, not greenfield builds.
- Every cutover is split into reversible waves with a validated rollback window.
- Knowledge transfer to your teams is a planned outcome, not a parting concession.
Why is security never decided by a single product?
Because an attacker does not face your products one at a time: they chain the points where those products meet. A correctly configured firewall does not make up for remote access without strong authentication, nor for a flat network where one compromised endpoint reaches the payroll server.
This is why we refuse to split an assessment into technical silos. The compromises we analyse almost never stem from a single spectacular flaw. They stem from a chain: a stolen credential, missing segmentation, logging that alerts nobody, and a backup reachable from the same network as the thing it backs up.
- Coherence across four planes. The network determines what an intruder can reach. Access controls determine who they can become. The cloud moves the boundary of your perimeter. Practices determine whether anyone notices.
- The existing environment sets the constraints. Designing an architecture on a blank page is an academic exercise. Securing a network core carrying twenty years of growth, with no downtime window, is another matter.
- Frameworks provide the shared language. We work with the NIST CSF, the CIS Controls and ISO 27001, so your decisions are defensible to an auditor and not only to us.
What changes when you work on a production environment?
The entire sequence. In production, the question is not which architecture is best but how to get there without breaking what works. That imposes a complete flow mapping before any change, and a rollback plan at every step.
The sequence we apply is almost always the same. Map first what talks to what, because existing documentation is invariably incomplete and cutting an undocumented flow is paid for in downtime. Then define the target trust zones. Then cut over in waves, each validated before the next, each reversible.
That method costs more time than a single cutover. In exchange it avoids the situation that makes security projects fail: an unplanned outage, a management team that loses confidence, and work frozen halfway through in a state less secure than the starting point.
What are your four domains?
Network and connectivity, cybersecurity, cloud and modernization, then automation and AI. Each has its own page. They share one requirement: working in environments where unavailability carries a direct, measurable cost.
- Network and connectivity. LAN, MAN and WAN architecture, segmentation, SD-Access, high-density Wi-Fi including metal-framed industrial settings. This is the layer that sets how far a compromise can travel. See network and connectivity.
- Cybersecurity. Zero Trust architecture per NIST SP 800-207, access control, dynamic segmentation, SASE, incident response. See cybersecurity.
- Cloud and modernization. Azure, AWS and hybrid migration and hardening, identity management, environment separation, control over out-of-jurisdiction data transfers. See cloud and modernization.
- Automation and AI. Event correlation, thresholds learned from real network behaviour, automated remediation within a validated scope, auditable logging. See automation and AI.
How does an engagement run, from audit to operations?
In four stages. Audit of the existing environment, design of the target architecture, deployment in reversible waves, then operation or knowledge transfer. Each stage produces an auditable document, because an undocumented architecture becomes opaque again at the first change of staff.
- 01. Audit and assessment. Survey of the existing environment, flow mapping, asset inventory including the assets nobody knew were exposed. This is the stage that produces the most surprises.
- 02. Design. Target architecture, trust zones, trade-offs stated with their costs. We document what we did not choose and why, because that record is what stops the same debate reopening in two years.
- 03. Deployment. In waves, outside service hours where the context demands it, with a validated rollback window at every step.
- 04. Operation or handover. Monitoring by our teams, full handover with documentation and training, or a hybrid model with on-call coverage on critical components.
How do you ensure the architecture stays maintainable after you leave?
Through documentation and handover, treated as deliverables rather than as a parting courtesy. An architecture only the firm that built it can operate is a dependency, not a security improvement.
Three things contribute concretely. Operational documentation written for the person who will hold the role in two years, not for the person who lived the project. Training of internal teams on the architectural decisions, not only on the procedures. And traceability of the choices, so a newcomer can understand why a rule exists before removing it.
It is also a regulatory requirement in practice: an audit, an incident recovery or a change of staff must not undo your security posture. Without documentation, they do.

Frequently asked questions
It is a model in which no access is granted on the basis of network position alone. In a traditional architecture, being "inside" was largely enough to be treated as legitimate, so a compromised endpoint could roam. Zero Trust, defined canonically in NIST SP 800-207, systematically verifies identity, device state and the right to reach a specific resource, on every request. For an existing organization, that translates concretely into segmentation, strong authentication and logging of cross-zone access.
A VPN attaches the user to the corporate network and then leaves them considerable freedom of movement inside it. A SASE approach attaches the user to the application they need, applying security controls at the access point rather than at the centre of the network. The practical difference shows the day a remote endpoint is compromised: with a VPN, the attacker inherits the user's network position; with a per-resource approach, they inherit only the user's rights on authorised applications.
That is the constraint in most of our engagements, and the method that makes it possible rests on three things: complete flow mapping before any change, a split into reversible waves, and a validated rollback window at every step. We work outside service hours where the context requires it. We do not present the absence of interruption as a contractual guarantee, because no honest provider can give that on an environment they have not yet surveyed: we present the method that makes it achievable and the fallback plan if it is not.
Yes, along with hybrid environments, which are the reality for most organizations. Our consultants are certified across the main ecosystems and we design within your internal standards and existing contracts. Since we do not resell licences, the choice of platform is discussed on technical and regulatory grounds, including data location and applicable law, rather than on our margins.
Yes, and it is a planned outcome of the engagement rather than an end-of-project option. Depending on your choice: full handover with operational documentation and training of your teams, monitoring managed by us, or a hybrid model where you run day-to-day and we retain on-call coverage on critical components. All three are legitimate outcomes, and we have no structural interest in keeping you dependent.
