QuantM is a cybersecurity company that helps owner-run businesses in Richmond Hill, Ontario know someone is watching their Microsoft 365, email and user accounts. We provide managed cybersecurity for York Region firms: 24/7 human-led managed detection and response (MDR) that monitors Microsoft 365, email, identities and endpoints, and acts when something looks wrong. People usually find us after a trigger: a cyber insurance renewal asking who monitors email, a client security questionnaire, or a staff member who nearly approved a fake payment request.
We are a cybersecurity-focused MDR and governance partner, not a general IT provider. Richmond Hill brokerages, clinics, accounting and advisory firms and technology teams use QuantM as the security monitoring layer beside their current IT support. Median MDR triage is under 5 minutes, and our email protection blocks 99.4% of phishing. The quickest way to see where you stand is a free 15-minute M365 Posture Review.
Richmond Hill is a city of owner-run firms. Brokerages and mortgage teams work out of Yonge Street and Major Mackenzie offices, clinics and dental practices serve the neighbourhoods around them, and technology and engineering companies fill the Highway 7 and Leslie Street corridors. Most of these businesses are too small for a security team, yet they handle money movement, personal information and client files every day, almost all of it inside Microsoft 365.
The pattern we see most often is a gap in ownership. Your IT provider keeps laptops, printers and licences running. Nobody is assigned to investigate an odd sign-in from another country on a Saturday, or a new inbox rule automatically forwarding mail to an outside address. QuantM puts analysts on that work around the clock, so a suspicious event is investigated and escalated instead of sitting in a log.
A search for a security provider tends to return a long list of general IT shops. The better test is what happens after an alert fires: who reads it, who investigates and who has authority to act. In Richmond Hill, where deals, patient records and client funds often move by email, those answers are worth having before an incident, not after.
There is also a practical benefit for owners who are asked to prove their controls. Lenders, insurers, larger customers and professional bodies increasingly ask how security is run day to day. Continuous monitoring, named escalation contacts and plain-language reporting give a Richmond Hill owner something specific to show, and they free your own staff from watching alerts between client meetings.
QuantM has one customer-facing office, at 100 King Street West in Toronto. We deliver monitoring and response to Richmond Hill remotely.
Closing instructions, deposits and banking details travel by email, which makes brokerages, mortgage teams and developers a favourite target for payment redirection fraud. QuantM monitors mailboxes for suspicious rules, risky sign-ins and impersonation so a spoofed message is caught earlier. It also gives brokers a clear answer when a lender or client asks how email is protected.
Clinics hold sensitive personal information on a small IT footprint, and staff cannot stop treating patients to chase alerts. QuantM monitors the Microsoft 365 accounts, email and endpoints that touch that information, without getting in the way of clinical work. It supports your privacy obligations and helps prepare the evidence reviewers ask for, but it does not replace your own responsibilities.
Accountants, bookkeepers and financial advisors keep tax files, statements and wire instructions in shared mailboxes and drives, and busy season leaves little time to inspect an odd login. QuantM watches identities and email around the clock and reports in plain language you can show a client or an insurer.
Software, IT services and engineering teams along Highway 7 depend on cloud consoles, collaboration tools and shared repositories, and larger customers expect proof of how access is watched. QuantM monitors identity and cloud sign-in behaviour so unusual access is investigated, and it helps your team respond to customer security questionnaires with specifics.
Independent insurance brokers and small law practices hold client confidences and policy or matter files in email. A phishing near-miss or a renewal questionnaire is often the first sign that monitoring needs an owner. QuantM adds that owner without changing how your people already work.
Starting is light. You keep your IT provider and your tools, and we add the monitoring and response on top.

Human analysts triage alerts 24/7. Median MDR triage is under 5 minutes.
When something is real, we escalate with clear next steps and help contain it, then report on what we saw and what changed.
Coverage follows where your data lives and where attackers usually get in.
Many Richmond Hill firms have a trusted IT provider or a part-time admin, and that relationship is worth keeping. QuantM is the dedicated security layer beside it: detection, investigation and response coordination, while your provider keeps the helpdesk, devices and everyday administration.
This matters most for firms with a part-time admin or a single IT contact. One person cannot watch sign-ins overnight, and they should not have to. QuantM handles the investigation work, tells your contact exactly what we found, and leaves the decision about devices, licences and day-to-day fixes with the people who already know your setup.
We agree who does what at the start, including who we call after hours and which actions we can take. You get one clear line of responsibility for security without switching providers or creating friction between teams.
It watches your systems for attacks and acts on them. QuantM provides 24/7 human-led MDR across Microsoft 365, email, identities and endpoints, so suspicious activity is investigated and escalated, not just recorded.
Those tools block known threats, but someone still has to review the alerts and act on them. Most attacks on small firms now arrive through email and stolen logins, which antivirus does not see. MDR adds people who investigate those signals around the clock.
We monitor mailboxes for the signs of business email compromise, such as new forwarding rules, unusual sign-ins and look-alike senders, and escalate quickly. No tool removes the risk, so we also suggest a call-back habit for any change in banking details.
Yes. We monitor the Microsoft 365 accounts, email and endpoints that handle that information and help you prepare evidence for privacy reviews. Compliance remains your responsibility, and monitoring supports it rather than replacing it.
Your IT provider keeps systems running. QuantM focuses only on security monitoring and response. Most clients keep their provider and add QuantM beside them.
It helps you prepare. Insurers commonly ask about monitoring, multi-factor authentication and email protection, and MDR gives you a clear answer on monitoring. Coverage decisions stay with your insurer. Bring your renewal questions to the posture review and we will map them to what is monitored.
Median MDR triage is under 5 minutes. Analysts work around the clock, and when an alert is real we escalate with clear actions and help contain it.
It is the usual starting point, along with Entra ID, email, endpoints and cloud accounts. We confirm scope in the posture review so you know exactly what is monitored and what is not.
No. Our one customer-facing office is at 100 King Street West in Toronto. Richmond Hill and York Region clients are served remotely, through your Microsoft 365 tenant and endpoint tools.
No. Agents' accounts are monitored through your Microsoft 365 tenant wherever they sign in from. Analysts watch for new devices, unusual locations and mailbox rules that forward mail outside the firm, and escalate what looks wrong.
