Start by securing company accounts and making recovery possible: enable multifactor authentication (MFA) for email, file storage, remote access, and administrator accounts; patch supported software; restrict access; back up critical data; and decide who responds if something goes wrong. Then add employee reporting, logging, and practice in line with your capacity. These are baseline steps, not a substitute for assessing your company’s systems, data, obligations, and risks.
What should a company do first?
Cybersecurity is ongoing risk management, not a one-time purchase or a guarantee against compromise. For a small or midsize business, a useful order is to establish ownership, protect identities, reduce common entry points, secure recovery, and prepare to detect and respond to incidents.

Start with an accountable business owner and a technical point of contact. The technical work can be handled by an outside provider, but the company should retain oversight of its systems and access. CISA’s small-business cybersecurity resources include guidance on roles and incident response.

How can you secure company accounts?
Require MFA first for administrator accounts, company email, remote access, cloud file storage, and accounts that handle sensitive information. Use separate administrator accounts rather than doing routine work with elevated privileges, and give each person and provider only the access needed for their role.
MFA methods do not offer equal protection. CISA’s small-business guidance orders its listed options from physical security keys, to authenticator apps with number matching, to apps with one-time codes, biometrics, and finally text or email codes. A security key is a strong choice when the company’s identity service and devices support it; confirm enrollment, administrative management, and account recovery before rolling it out. App-based methods can be practical alternatives. Treat text and email codes as fallback options where stronger methods are unavailable. CISA’s guidance says, “Businesses should aim to use a phishing-resistant MFA method.” See CISA’s MFA guidance for small and midsize businesses.
Plan for lost phones or keys before enforcing MFA: decide how users prove their identity and regain access, and protect recovery methods as carefully as the primary sign-in. A password manager can help people maintain unique credentials; CISA’s small-business resource hub includes password-manager education.

How can you reduce common ways attackers get in?
- Patch and update. Turn on automatic updates where appropriate, track software that is no longer supported, and prioritize urgent fixes for internet-facing systems.
- Make reporting easy. Teach employees to recognize suspicious messages and report them promptly. Make clear that they should report a click or disclosure immediately rather than hide it; a fast report gives the company a chance to limit damage.
- Limit access. Review who has administrator privileges and vendor access, remove access that is no longer needed, and use restricted accounts for service providers.
CISA’s four-essential-mitigations fact sheet is written for state, local, tribal, and territorial government entities, not as a company-specific standard. Its practices can still corroborate the value of patching, MFA, and other basic mitigations; companies should apply them according to their own systems and exposure.
How should you make backups useful for recovery?
Back up critical business data and system configurations automatically and continuously where feasible. Keep a copy air-gapped from the organizational network so that a network compromise is less likely to reach every recovery copy. CISA’s StopRansomware Guide recommends automated, continuous backup of critical data and configurations, including an air-gapped location.
Decide who can restore systems and how the business will operate during an outage. Test restoration: a successful backup job alone does not establish that files and systems can be recovered in a usable state. Set retention and recovery targets based on business needs and applicable obligations rather than adopting a universal number.

How can you detect and respond to an incident?
Choose which systems need logging, who reviews alerts, how records are protected from unauthorized access or deletion, and how long they are retained. Logging without a review and response process can leave suspicious activity unnoticed. CISA notes: “Early detection of unusual activity is key to preventing data breaches, ransomware, and other costly incidents.” Its business logging guidance covers these practices.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Assign incident-response roles and contact details for technical response, leadership, communications, legal support, and business continuity. Keep a short first-response checklist available offline, including how to contact your IT provider and preserve evidence. Create and practice a plan for plausible scenarios such as a compromised email account, ransomware, or a lost device. CISA recommends exercising incident-response plans at least annually in its Cross-Sector Cybersecurity Performance Goals; a small organization can begin with a simple walkthrough.

If you lack internal capacity, a managed IT or security provider may help with monitoring, maintenance, or response. Outsourcing does not remove the company’s responsibility to govern access, backups, and recovery. Before contracting, clarify:
- Which systems and services the provider monitors, and what hours response is available.
- Who controls administrator accounts and how provider access is restricted and reviewed.
- Who manages backups, tests restoration, and leads incident escalation.
- What reporting you receive, how incidents are communicated, and what the contract requires.
CISA’s managed service provider guidance recommends MFA, least privilege, restricted service-provider accounts, and air-gapped backups. It does not rate providers or establish a vendor shortlist.
What free CISA resources can a small business use?
CISA’s small-business resource hub lists no-cost guidance and services, including Cyber Hygiene Services for vulnerability and web-application scanning. CISA also offers SCuBA for assessing supported SaaS configurations; check the SCuBA project page for current scope and supported services. Availability, eligibility, and tool details can change, so verify them directly with CISA.
How should larger or regulated organizations adapt this baseline?
The steps above are an SMB-oriented baseline, not a security audit or compliance determination. Larger or regulated organizations should adapt priorities to their exposure, systems, data, contractual obligations, and applicable rules. The requirements vary by geography, industry, and customer relationships; confirm which laws, insurance conditions, and contract controls apply with qualified counsel or compliance staff.
