  1. Cybersecurity
  2. Phishing protection
Phishing protection for US businesses

Phishing protection that layers: filter the obvious, limit the damage, train for the rest.

Email filters catch the mass-produced attacks; the well-crafted phish that redirects a payment slips through. Real protection is layered: technical controls in Defender for Office 365 and your email authentication records, identity controls that stop a stolen password becoming a compromised account, and a human layer of awareness training and simulated phishing that is measured rather than assumed. We deliver all three, remotely, as one program.

Phishing protection scope

Eight controls across email, identity, and human layers.

Phishing protection is layered. Technical controls filter the volume; identity controls limit the damage when an email gets through; human controls reduce click rates over time. Each layer covers the failures of the one before it.

Defender for Office 365, tuned

Safe Attachments, Safe Links, anti-phishing policies, anti-spoofing and impersonation protection, configured around your sector, your communication patterns and the people attackers would actually impersonate rather than left at defaults.

DMARC, SPF, DKIM enforcement

Email authentication configured to reject spoofed inbound mail and protect your own domain from being used against your customers. DMARC reports monitored, then quarantine and reject policies enforced in stages once authentication is stable.

Anti-impersonation and BEC protection

Business email compromise detection: lookalike domains, display-name spoofing, payment-redirect attempts, finance-team impersonation. Per-user impersonation protection configured for executives and the people who approve payments.

URL detonation and attachment sandboxing

Suspicious URLs detonated before delivery and attachments scanned dynamically rather than only against signatures, which is what catches the payload nobody has seen before.

Phishing-resistant MFA

When somebody does enter credentials on a fake page, phishing-resistant MFA (FIDO2 security keys, passkeys, certificate-based authentication where feasible) stops the stolen password becoming a compromised account. This layer is what your cyber insurer asks about first.

Post-compromise monitoring

If an account is compromised anyway, the signals are watchable: unusual sign-in patterns, impossible travel, new mailbox forwarding rules, unexpected OAuth application grants. Monitoring those turns a breach into a contained incident.

Security awareness training

Recurring micro-training on phishing recognition, vishing, smishing and social engineering, role-based for finance, HR, executives and IT, because those groups are targeted differently and generic content does not stick.

Simulated phishing campaigns

Monthly simulated phishing sent to your staff, with click rate, report rate and credential-disclosure rate tracked over time. The trend, not any single campaign, is what shows the human layer improving.

Why businesses route phishing protection through us

Four reasons US businesses choose GR for phishing defense.

Microsoft-native, tuned for your environment

Defender for Office 365 works for everyone in default configuration, and defaults protect nobody in particular. As a Microsoft partner we tune it to your sector, your false-positive tolerance, and the specific people and vendor domains that appear in your payment conversations.

Technical and human layers together

Most providers do one: technical filtering or awareness training. The combined effect is multiplicative, because the filter shrinks the volume reaching people while training changes what people do with what remains. Running both under one accountable team is the point of the program.

Measured, not asserted

A monthly report shows click rate, report rate and filter activity trending over time, in language your leadership can read. That trend is also exactly the evidence a cyber insurance renewal or a SOC 2 auditor asks for, produced as a byproduct of running the program.

Role-based training, not one-size-fits-all

Finance teams trained on payment-redirect scams. HR trained on resume-attachment malware. Executives trained on whaling and BEC. IT trained on credential harvest and fake vendor support. Higher relevance produces higher retention, which is what changes behavior.

Who needs phishing protection most

Six business profiles where phishing protection is critical.

Finance and accounting departments

The highest-value target for BEC and payment-redirect scams, and often the entry point for ransomware. The FBI has tracked BEC among the costliest cybercrime categories reported by US businesses for years.

HR and recruiting

Resume-attachment malware, fake-applicant social engineering, and employee impersonation during onboarding, when new hires expect unusual requests.

C-suite and executive teams

Whaling attacks, executive impersonation, and urgent wire-transfer requests that trade on authority and time pressure.

IT and engineering teams

Credential-harvest attacks, fake vendor-portal emails, and fake Microsoft-support social engineering aimed at the accounts with the most access.

Customer-service teams

Customer impersonation, account-takeover precursor emails, and fake refund-request schemes against the people trained to be helpful.

Regulated and insured firms

HIPAA-covered entities, firms under the FTC Safeguards Rule or NYDFS Part 500, SOC 2 candidates, and anybody renewing cyber insurance: phishing controls are a recognized safeguard every one of those processes asks about.

How a phishing protection program rolls out

From audit to ongoing operations in 6-8 weeks.

  1. 1

    Phishing-readiness audit

    1-2 weeks

    Review current email security configuration, DMARC posture, MFA enforcement, training history and recent incident pattern. Output: a written gap report with a prioritized remediation roadmap, yours to keep either way.

  2. 2

    Technical foundation build

    2-3 weeks

    Defender for Office 365 tuned, SPF, DKIM and DMARC configured with a staged path to enforcement, impersonation protection populated per user and per domain, and MFA enforcement gaps closed with phishing-resistant methods where feasible.

  3. 3

    Post-compromise monitoring activated

    1 week

    Sign-in anomalies, new mailbox forwarding rules and OAuth application grants watched, so a credential that does get phished is caught in the minutes after use rather than the weeks after.

  4. 4

    Baseline training and first simulation

    2-3 weeks

    All-staff baseline training, role-based deep-dives for finance, HR, executives and IT, and a first simulated phishing campaign to establish the click-rate baseline. Results communicated to leadership with the trend that follows.

  5. 5

    Ongoing operations

    Continuous

    Monthly simulated phishing, quarterly micro-training, a monthly report covering click rate, report rate and filter activity, and continuous monitoring for post-compromise signals. The program runs on a rhythm, not on memory.

Phishing protection FAQ

What buyers ask before engaging.

Necessary but not sufficient. Filtering handles the mass-produced attacks well. What gets through tends to be the highly targeted message, spear phishing, BEC, whaling, where the social engineering is the threat rather than the malware. Human-layer controls (awareness training, simulated phishing, a reporting culture) and identity-layer controls (phishing-resistant MFA) handle the residual risk that no filter catches.

Phishing is email-based. Vishing is voice: phone calls impersonating IT support, Microsoft or banks. Smishing is SMS-based, including the fake toll-payment and delivery texts that circulate constantly. BEC, business email compromise, is a specific phishing type using executive or vendor impersonation to trigger fraudulent payments. All are addressed in awareness training; technical controls cover phishing and BEC.

Done badly, as annual compliance e-learning, not very. Done well, role-based, with simulated phishing, micro-training and a measured click-rate trend, it changes behavior visibly within months. The key is measurement and iteration rather than a one-time training event, which is why the simulation cadence and monthly reporting are built into the program rather than optional.

Done with the right tone, no. Communicate the program transparently before launch, frame results at the team level rather than individual shaming, and deliver just-in-time micro-training when somebody clicks. Most teams come to appreciate the visibility once they understand the threat is real, and reporting rates rise, which is the behavior you actually want.

A real risk if done badly, which is why we deploy in stages: monitor-only first, quarantine for low-risk senders next, and reject only when the reports show legitimate senders are authenticating cleanly. A typical full-enforcement timeline runs 3-6 months from start, and the staging is what protects your invoices and newsletters from being caught in your own net.

Because the goal of most phishing is credentials, and MFA decides what a stolen password is worth. Standard push-based MFA can itself be phished through real-time relay pages, which is why the program pushes toward phishing-resistant methods, FIDO2 keys and passkeys, for the most targeted accounts first. It is also the control cyber insurance applications ask about most directly.

Technical controls primarily target the email vector. Vishing and smishing are addressed through awareness training, with role-based content for the finance, IT and customer-service teams who actually receive those attempts, and through process controls such as verification steps before acting on any phone or text-based payment request.

The monitoring layer exists for exactly that. Unusual sign-in patterns, impossible travel, new mailbox forwarding rules and unexpected OAuth grants are the signals a compromised account produces in its first hours, and watching them is the difference between resetting one account and investigating a month of silent mailbox access. Where an incident is live, our incident response engagement takes over.

Directly, because each asks the same questions this program answers with evidence: how is phishing filtered, is MFA enforced, are personnel trained and is that training tested. Training records, simulation trends and configuration evidence come out of the program as a byproduct. We are an IT services firm, not auditors or lawyers, so your compliance advisors own the interpretation; we own the controls and the evidence.

Yes, visibly. Insurance applications ask about MFA, email filtering, awareness training and simulated phishing by name, and the answers move both insurability and terms. A running program lets you answer each question with a specific control and a date rather than a hopeful yes, and the monthly report doubles as the renewal evidence pack.

Scoped per engagement: the licensing you already hold (often Defender for Office 365 is already in your Microsoft 365 subscription) plus the engagement for tuning, training delivery, simulation operation and monthly reporting. It is frequently bundled into a managed IT or wider security engagement, and we will tell you in the first conversation what you already own.

Simulated phishing results (click rate, report rate, credential-disclosure rate), filter activity and notable blocks, top-targeted users, training-completion status, and any post-compromise signals investigated. A one-page executive summary up front, technical detail behind it, written for management rather than for engineers.
